From what I know, I will hold onto the bitcoins, everything will be sent from the seller to the buyer.  If the buyer brings up any problems in the process, I will THEN review over the files and look for any problems.  I can get my friends to help with this but I guess it would be better to have an escrow with full coding knowledge (that's not me)  If no major disputes related to the code itself were to occur, i think I would be fine for this job.

Cheers!
