Which Software/Programs to Use if I Want to be an Escrow Merchant Provider??

[vbenhancer]

you can purchase a complete system for freelancers or some personal ads system that integrate Escrow, but they are not numerous, because the Escrow company is really stiff on approving third party products... security risks.

but for vBulletin, nobody ever created one to be released publicly

this one can be integrated with vBulletin, in some way... http://www.alstrasoft.com/escrow.htm
