Am I right to think that what you're offering here is to send our client's funds to a random person on the Internet and that would be secure and trustworthy? Alas, this is not how money business works. These funds are not ours, they are our client's, first and foremost, and sending them to an unknown third party would be a disaster.
No, you are wrong. What he is offering is the use of a trusted escrow on this platform. These are individuals that have proved their trustworthiness over several years in this forum. You are not trusted, they are. You lack credibility, they have it in abundance and have held amounts larger than 11 BTC.
