Dont give up. There are some resources there that MAY be able to help you, you just may have to search long and hard. Here is arizona, there is a local business Association called ASBA. They have created a large group guaranteed issue health insurance program in which any member company can get access to health insurance at a discounted rate. Guaranteed Issues means that regardless of your conditions that you will be allowed to enter the program without additional penalties or price increases. I don`t know if this is available in your area but its worth looking into. In this particular association, you can get access to this plan even if you are a sole proprieter. Look around a business associations and see what is in your area.
Good luck to you. BTW...AZ is considered the top ranking Entreprnuer state, maybe it`s time to consider a move :)
