Bitcoin expert developer here? Develop Bitcoin escrow add-on/script

[XYZ500]

I'm looking for an expert Bitcoin developer who can develop a Bitcoin escrow add-on/script for a marketplace forum, just something similar to LocalBitcoins.com escrow. This requires extensive Bitcoin knowledge so I'm guessing any developer who is not very much familiar with Bitcoin will not be able to do this. I'm not writing many details here of what I want because I've already mentioned that I want a clone of LocalBitcoins.com escrow and any expert Bitcoin developer will know what I am talking about. When my users buy/sell with each other on the forum, I want to offer an escrow service to them to be safe and that is what I need this for. Anyone here who can do this?
