Until recently I had an excellent group health PPO for my s-corp through my local Blue Cross affiliate in Philadelphia. I made my wife an officer of the company so we would have a qualifying group (i.e., two or more members -- she did work for the company anyway, but I simply formalized her role).
The medical and prescription coverage on this plan was outstanding (no dental or disability). I had myself and our daughter on my policy, and my wife had an individual policy. The monthly premium for the individual plan was $315.48, and the parent and children plan premium was $548.54 (these premiums were after an increase on 1 June 2005). The cost of my wife's premium was fully deductible to my business and my premiums were deductible as an adjustment to income on my 1040, provided I didn't deduct more than I paid myself in wages (usually not an issue). I have a separate, individual long-term disability policy to provide $6500/month in income replacement with a 90-day wait for which I pay $250/month (I can't recall who writes that policy -- Berkshire perhaps).
If you're single, the only challenge (apart from being profitable) is finding a second person to round out your group. You need to be able to make a "reasonable" claim that this person works for your business (I don't think corporate officers necessarily need to be paid, but you could also have the person on 100 percent commission with unattainable goals). A big plus for you is your relatively young age, since many group policies have begun pricing policies based on the demographics of the group, rather than broad demographics related to geographic area.
I recently gave up my own business to work for a big corporation, and the health and prescription benefits I now receive are no better than my Blue Cross policy.
Good luck.
