I am self employed and purchase my own insurance.... It is one tough world out there .. sometimes even finding someone who will quote you insurance.
I spend LOTS of hours ... after BCBS who I had a policy for 4 years and NEVER had one claim... decided I was now uninsurable since I changed the name of my company .... it was unbelievable !!!! ( I finally figured it out ... I was now over 50 , and they wanted any excuse to drop me) .
One word of advice never go one minute without or new insurance companies will not even look at you ... as they think you are scrambling for insurance because you have an issue you need insurance for.
I finally found a policy with Etna ... not a great plan but will cover a major need on a 80/20 basis ... I pay the 20 percent.
I suggest you find a group through what ever means you can...AARP .... Some credit unions have a plan.... do alot of homework.
