How can I start a small Credit Card Company?

I am curious to know how much start up money would be needed to start a small Credit Card Company. I am interested in extending credit with Secured Credit Cards with low limits for individuals looking to establish or re-establish credit by a secured credit card. Also I have thought about prepaid debit cards for those in chexsystems and cannot get conventional checking accounts.

Any help?
What I mean is not to broker, but to be able to start a very small company directly.

as a broker or the one lending the money?

if a, contact lenders.
if b, you will need many millions of $.
