I just checked out your site and it's still basic. It does not give anyone the guts to use it.
Do you have what it takes to compete with the likes of Agoradesk, Localcoinswap, localmonero etc.? Have a look through the site I have just list, you might get some inspiration from them.

Also, LocalBitcoins is a bad example of a p2p marketplace that inspired your work, especially when they introduced KYC verification.
