Hi H.. I am self-employed and have myself and my son on Blue Cross Blue Shield (individual policy). Your premium will depend upon how high you want your deductible (ie $500, $1000, $1500, etc...). My deductible is $1500 and I pay $440/month. Keep in mind that is was much lower when I first started (I've been in business about 5 years), however BCBS goes up every renewal period.
I wish I could tell you that there is a great policy out there for self-employed people but I have yet to find one.
Can you get on your husband's policy through his work. That would be your best bet if it's not too pricey.
On another note...welcome to the world of the self-employed Mom's. I'm part of a networking/support group of women who are mothers and self-employed called the Network of Enterprising Women. Check us out at www.ntxnew.org and when you are up and running perhaps you can visit with us at a meeting.
Good luck on your new business!
Sincerely,
K.
