Tell all the persons owing you money that they have exactly 2 weeks to render payment or you will take them to small claims court.(You can always try 1 of the on-air judges like Judge Judy, if you think you may lose.Cause on those shows,both the defendant AND the plaintiff get paid like 2grand apiece for letting them tape it.The judgement is taken from that persons fee for appearing.If they owe you 2 grand or more and you win,you could walk away with 4 grand and they walk with zero.

Either way,you let each deadbeat know that you will NEVER lend them a cent again and for them not to even ask.Personally I would totally disown them,I've done it on more than 1 occassion when someone stiffs me on a loan.Block their calls,refuse to answer the door if they come over, even call the cops on them if they keep pounding on the door instead of taking the hint and leaving.
