I think this is your biggest obstacle - trust.

It's hard for any service of this kind to gain the trust of users when it comes to cryptocurrencies. Even more when it comes to an anonymous user like you.
I don't want to jump to conclusions here and call your project scam, but I'm surprised you decided to use a brand new account to promote this project when I'm sure you've been in the crypto world for a long time, and you probably have other accounts on this forum.

There are many respectable members here offering escrow services. If you were one of them, you'd probably have a much better chance of successfully launching this kind of service.
