Looks cool. I would be interested to be a part of your site

Me too , i'd like to partecipate.
Probably the best thing to do is set up some example escrows.
For anyone interested PM me with 2 example email addresses you have access to, one of a buyer one of a seller. I'll create an escrow agreement.
When the agreement is created in onchain it will send out the invites to the 2 addresses ( and also to to me as I'll act as an escrow agent).
You can then see how the multi sig creation stuff works. I'll fund the bitcoins
