You should contact Pazazz photography in Texas to see if they will travel. They only do gymnasts and are really good. They come to our gym as well as others every year.
Most of the NE Meets seem to use Champion Photography. The get some really great shots especially moving ones like Leaps etc. They usually have some deals since they are at most of the larger meets. I've purchased a few from them of my daughter.
Try digitalmagicphoto.com . They're based in the south, but they did our state meets the last few years and did a good job. Plus, they've handled some large sporting events. Plus lots of online galleries you can view. Good luck!
