To OP no matter how much reputation you have in LbC here your trust level is completely zero so you have to opt for trusted escrows from bitcointalk if you're really intended to actual trade.
Exactly my thought. If OP is dealing with someone on localbitcoin, they should get their escrow there and if dealing with someone on BTT; they should get their escrow here. No two ways about that. Trust isn't transferable from one platform to the other. Another issue OP is a fresh newbie account registered less than a week ago with only five posts. It doesn't speak well when it comes to financial dealings.
All the trades on LBC comes with automated escrows and 1% trading fee so there is no need to worry about escrow there cause chances of holding without a valid reason can be simply broken by the proof of payment made. But we need to be careful while choosing the person who we wre trading with most people ask KYC these days and no third party transfers,and more restriction to avoid money laundering.
