Might be difficult.
I checked into it before, IIRC I had to somehow sign up my business with the credit agencies. This, of course, took more money than it was worth.
Collection agencies didn't seem like much help either IIRC. THey wanted a contract for all outstanding debt, not just whatever I felt like having them collect.
But its been quite a while since I checked it out.
Good Luck with it,
Fern
