Website for player to player transfers safely?

Hey all I am a player in the US who has been away from playing because of the restrictions US players have had with depositing.
First time posting here, maybe someone is familiar with this or can help me.

I am looking a website that is safe for player to player transfers. Virtually selling money in your poker account and having it transfered to your bank account or paypal.
Which poker clients allow this to happen does blackchip?

Is there a trusted site that could hold the money until the player to player transfer is complete?

Thanks for any help
Brett

Americas Cardroom
Black Chip
Juicy Stakes
Lock Poker

and most ROW sites if you're not from US.
