It doesn't matter how much it costs anyone because your circumstances and needs will be wildly different than others, and you may qualify for subsidies.
I would figure out how much your current health insurance is (both the employee and employer contribution). This is the amount you would pay if you quit your job and went on COBRA. You can be on COBRA for 18 months and it's typically cheaper than finding an equivalent plan on the marketplace. That gives you time to grow your business and figure out a long term health insurance solution.
I've found the opposite, though it likely depends on how "good" your insurance was. My COBRA was around $800/mo for a single person but that was essentially for a zero deductible plan.
I could get reasonable short term plans for about a quarter of that. As a healthy individual that was definitely the right choice for me, but if you have high utilization already it might not be for you.
But... it's not "expensive"... It's just the price. And many people never see or think about it because "employer" pays some/most/all of it. Until... you don't have an employer. Then it seems "expensive". But... the price has always been there, we just don't see it sometimes.
Employer-involved insurance is one of the biggest things slowing social progress, imo.
