Well... First item that comes to mind is to create a Web Design agency.

Also, you can expand into traffic + conversion management + maybe hosting + high deliverability email management... for your continuity income.

Tip: Always, always, always design your ad-hoc hourly work so this drives to continuity.

Tip: Just scan through Clarity + find Q&A threads which look like the person responding can be helpful. Then book calls with each of them to do a quick call with all 3x of you to help you rough out a design for your business.

Tip: Partner with other agencies for referral business.

Example: I focus on hosting high speed, high traffic, WordPress hosting + high deliverability, custom, email systems for clients with large lists.

I partner with many Agencies, who do traffic buys, ad buys, site design.

You might find partnering with other Agencies to be a good model for you also.

Tip: Scan Clarity for posts I've made about abusing... er, I mean hyper-using https://Meetup.com for lead generation, so once you work out your organizational details (should take no longer than a shared dinner for this), then use my Meetup lead generation techniques (mentioned in many previous answers) + you'll have more work/money than you might have imagined.

Welcome to the wonderful world of Agency work!
