Are you 100% self employed with no connection to any organization at all? Any professional affiliations? Usually industry affiliation groups have some sort of group plan available.
If not check out
the national association for the self employed. i'm not a joiner so i don't belong, but i didn't check them out a few years ago. as long as you aren't thinking about adding more kids they have some ok insurance programs available.
Also check with you state. some states (like AZ) have an insurance program for self employed people. they don't advertise it, but the coverage and costs are actually quite good.
