You can be whatever you want to be but it would be foolish of anyone to ignore the community FREE escrow to patronize a paid escrow service. Their loss.
If there is free escrow service in the local board then it is better for all their local board members to use it and the Op should used it to initiate the process it he want to be an exchange in the local board. Then another reason why go dey the process na the escrow matter, we know that in centralized exchanges or normal p2p we normally use, the transactions were very fast but in this because of the escrow as the third party there will be more delays in the transaction but it is more saver.
Once there's confirmation from seller and the buyer, escrow triggers, seller/buyer settle fee based on ToS. Takes only a few steps.
