I think you are still too early before committing to hiring a VA or cold calling. I read the other responses and I think they were good ideas, but again - you are still too early, let me explain.
My first thought was that if you are asking whether or not to hire due to needing clients, was that it showed lack of clarity and focus still which as an experienced marketer, I run a hybrid global marketing agency, tells me that you are still trying to also figure out who your best potential clients can be. You may be even still creating/solidifying your actual product delivery.
Create a buyer persona and buyer journey profile, pair/match that persona with your services/core expertise. Then go to work on reaching them...
For context -
As a business owner, professional coach you will have generally 3 steps:

Step 1:
Find the perfect fit for your expertise to the need by considering these factors:
a) Customer Pain
b) Customer Pleasure Goals
c) Labor Based Solution
d) Information Based Solution
** Find the right marriage for the pain customer is trying to solve such as divorce, but would they also love to have maybe a stronger marriage instead of just surviving? or bounce back harder? with a hotter/better soulmate? combine the problem with their end optimal goal (if anything it helps for marketing purposes to use as hook for attention on an ad or post, article headline, etc)
** Then decide if you will be providing a labor based, done for you, approach or an informational approach - how you can implement better with my guidance approach.
The most profitable solutions tend to merge both the information and labor aspect.

Step 2: Create the right tools needed to be able to address the questions that a prospect client will have for you - create landing pages, Clarity, Facebook groups, be a guest blogger/speaker with another authority in your field and begin a branded relationship that way, create videos and write articles that are relevant to your topic but are not your exact topic - as to cast a wider net of exposure, indirectly...
Essentially: Create a hook --> Develop a Stack --> Screening for best clients
** A stack is typically referred to as the content, answers to the possible questions, a behind the scenes but not complete show of what you do or the tools or process used - enough to give someone the opportunity to understand and appreciate what they would be getting w/o giving it all so they can just go do it themselves- just enough of answers and motivation whether is through email, landing pages, Facebook groups, etc.
on the Screening - you are essentially seeing the best fit for your potential clients to see who is willing to pay what you're worth, while committing 100% to the effort and time needed (this avoids you headaches and sudden loss of income) so that you and the prospect close only when both are comfortable with the process and each other - the best way to do this is through an automated system or hiring a marketing team to help you (biggest reason we get hired is due to lack of expertise and time constraints)

Step 3:
Enrollment - again simply, aim for automation.
Remember to not sell them, nowadays people want to come to buying terms on their own, so we create content that generates leads, we don't sell we lead. - inbound marketing.

Typically, people I coach or small businesses we help are stuck in the first or second phase of their small business. The phases are usually::
Generalist small business:
you start and try to do a lot for whoever wants to hire you because you need money. This is time capped, thus revenue/profit capped.

Specialist Do it For You-er:
someone who may narrow down services and charge a little more.. again capped.

Specialist Consultant: This is actually where me and my Unthink team fall under, Specialist Consultant Group - you narrow your focus, charge flexibly from high to low, but you get hired due to a person but work is done by a team, in some cases this is where someone starts hiring contractors.

Specialist Consultant Suite - This is a different model than the consultant group, not the next step but just an alternate - in your field this is very common. Coaches with enough revenue in place tend to invest in fully automated systems from lead generation all the way to product delivery of a suite, such as a video course or packaged mass produced training product.

You have to try to decide what you want to fall under and build a funnel, following the steps above so that you can have more chances of converting visitors into leads and into loyal customers. Then you use articles, videos, twitter, instagram live, live facebook groups, to drive awareness to yourself, and you drive traffic to your landing hook page or videos, capture contact info, follow up, follow up, ask, etc - so that ouf of 1000k exposures, you may get 200 visits, maybe 50 leads, and out of those maybe 3 or 4 clients - which is a good ROI, believe it or not lol.
If you don't get leads after your first 2k or 3k etc, keep going - get that number to measure off -see how many visits it takes to capture 1 lead. That's your starting point and made modifications to reduce that ratio to 800:1, then 500:1, etc, etc...

Find that gap between where clients are and where they want to be, answer/address those hurdles on your promotional material and content and help them get clarity on how to fix their situation. How to fill that gap.
