I know you from PD and Stake but you see, here people will not trust you with sending collateral directly over to you since you dont have any prior trade feedback. So it works that way that if someone is offering a collateral decide whom to use as an escrow to hold the collateral for the loan period.
Link this in your OP:
Recommended bitcointalk escrow servicesJust make sure not to give you loans without collateral, we both know how that ends and I can assure you that there are at least 100times more scammers than legit borrowers here than Stake forum.
But anyway good luck on your lending service.
