Why would anyone need you if they want to make a peer-to-peer bet? Since you're not funding it yourself your service is useless and 10% is way more than any reputable escrow would charge for escrowing a simple P2P bet.
All these "services" that you're coming up with sound more and more like scams. Stop before someone flags you.
