You've gotten an interesting, mixed batch of answers to your question.
Here's what I would personally do:
1. Think of a skillset that you posess, or would like to develop, that compliments your venture and what business you plan to do. (Consider the role you plan to hold in the venture down the line.)
2. Get a job that actively engages that skillset (for example, if you think sales is that skillet - perfect, get a sales job and get the experience & development you need, while being paid for it and making ends meet.)
3. Apply your newfound experience and cashflow to supplement your venture.
I'd love to continue the discussion on a call and hear about your personal situation.
Personally, I'd suggest for you to read the E. Myth by Michael Gerber, Secrets of Closing the Sale by Zig Ziglar and F.U. Money by Dan Lok.
You'll get a healthy dose of actionable information alongside a good serving of perspective reality.
I'd start by really pin-pointing your MVA's (Most Valuable Activities) or as I like to call them, your DRPA's (Direct Result Producing Activities).
As a business owner, you need to make more money, so focus on doing just that. Think "what is the best role for me to take on, where I can influence the business, but it's not dependent on me for operation & revenue?"
While I won't second others' suggestions to go to Freelancer or hire VA's - I want you to first understand, what exactly it is that you need outsourced. How much will it all cost? Are you willing to take a lower margin, but take the gruntwork off your shoulders?
My policy is: if you're doing something that doesnt equate to more $ for your business, at the end of the chain...you souldn't be the one doing it.
Before you ask "how do I get more clients?" Look at your current revenue model, can you shift it a bit, and up your engagement with existing clients along with their value in revenue.
Crunch the numbers, see what works and what doesn't. If you need an expert eye, I'd love to get on a call with you to discuss your business model and show you a few things that you can do to make the shift.
It really depends on: what business will you be doing, and who will you be doing business with?
Personally, in my carreer - I work alongside some of the most brilliant executives & business owners in Canada. My experience leads me to believe that a formal education gives you very well-rounded start in most areas of business alongside more depth of understanding. It does well to answer the question of "where do I start & what do I need to know?"
In entrepreneurship, information is leverage, and leverage is key. So, if you see yourself in a vertical where the sort of information offered in most traditional business schools will be of benefit, and you have the financial ability to commit to going back to school for this program - I don't see why not.
At the same time, building experience ontop of that information or education is where you will really shine. If "the price is right" for you, and you don't see a viable alternative - do it. But it's most definitely not the only option.
Marketing & Sales. A lot of entrepreneurs are "doers of the thing" but at some point, you're forced to take the shift and become a "marketer of the thing".
Think of it this way: You can have the best product on the market, but it doesn't matter if noone knows about it.
Ofcourse, there are so many other important bits I'd love to tell you about - but, start with these and you will see traction, the rest will follow.
