Jason,
I just did a mapquest from my location to yours and came up with 2600 miles. Depending where the airplane is located in NJ it will be at least another 200 miles and perhaps 350 miles to Atlantic City area. At $3500 your estimate is coming in well under the typical $1.50 per loaded mile. You could do the driving yourself and get the cost down to about $2500 or so depending on fuel burn/lodging cost. That's about 5 days on the road doing an average of 1,000 miles per day. I struggled with going to Texas for an unfinished Speedster kit and there was just no way to get the transport costs down to $2,000 with me doing the driving and that's assuming no unforeseen hassles which is probably not realistic. I've done a couple of these transport deals and it comes down to racking up miles on your vehicle and maybe getting minimum wage for your time. That's the "UP" side. Good luck.
