You'll probably get more response after people get to know you. Kinda asking a lot to look for a volunteer to take a day away from their own projects for someone they don't know. Don't mean to come off as an ass, but thats how a lot of people see it.
You can take that for what its worth... I'm one of those on here along with a lot of other that have worked on a lot of other peoples jeeps for them. However they are people that I've seen around and gotten to know first.
