This sounds like you'd be better off without a free trial at all. Charge a reasonable fee for unlimited use for a day or two. That way people would feel like they're going to be able to do whatever they need because its unlimited, but you get some renumeration. Just my first thought. i hope you figure something out. Best of luck to you.

you mean like charge a $1 for 2 day trial of unlimited use?

or give 14 day trial before card is charged.

nobody is going to put their Cc in to pay you one dollar. charge $20 for two days. no trial. charge up front. but honestly, you probably shouldn't be listening to me, i'm just thinking out loud
