Nope, those guys are useless. I'm talking about an actual automotive paint supply place. Where the body shop would go to get paint. I called a few places in your area. They're not cheap, but FinishMaster in Jersey City will do it for you. But it's not cheap. They quoted like $40 a can... There might be some other place local to you that would be more reasonable.
They'll need a clean flat area at least 2in x 2in to put the camera on. I might be able to take my Hamilton box up to the place that's local to me and get the paint code for you. Let me know if you're interested. That box has the yellow green color to it.
