Welcome!
You have come to the right place--and in order to get the full benefit of this site, I suggest that you register with us.
And trust me when I say that PDL's are something that we know ALOT about here. In your situation, I would make a list of the PDL's that you have first, and then indicate whether they are storefront or internet.
The reason this is important is because in most cases, storefront PDL companies are usually licensed in your state and should be paid first, since there is a greater chance of them taking you to court.
And if you want information on internet PDL's, do a search on them here, and chances are that we've already got threads on them.
I really hope you register and come back!
