Can you add in how much the service charges? If it is 0$ then make it that. I get the feeling* that you're going to hold my items for ransom after someone finds them. I suggest you make it obvious that you're not a bad actor.

* I think the negative connotation comes from your logo's dollar sign, $. It looks like a scammy pay-day loan or something. I'm not saying to change your logo, or your website sucks -- it looks awesome! -- I'm just letting you know my take on it.
