What do you think about my idea?

I would not recommend this.

Mainly only newer players and desperate players will be interested in your idea. Both of which are prime candidates for scamming you.

This is different to normal server transactions such as players buying cars from each other. In those cases, users are likely more experienced, less desperate, and the transaction is complete between both parties within a minute.

With your idea, the transaction is not complete within a minute. You send the money, and then you have to wait for an undefined period of time. Maybe they get themselves into debt. Maybe they stop playing or get banned. Admins do not have the time to bail you out continuously, and in some cases it would actually be impossible to bail you out.

Again, I would not do this.
