The problem is that these laptops could be worth less than what youre asking (you shouldve post pictures publically with your name and timestamp written on a piece of paper showing what youre offering, and maybe even the models of such laptops). On top of that, one would have to be responsible for shipping the device to and from the lender. If you really need the money, going to a local pawn shop may be better since they will be able to see the device in person and determine how much to lend you.
