INFO-
I found a Camera place that repairs cameras and does Free estimates. they're very good and has been mentioned in the New Yorker Magazine as one of the top camera places for repairing cameras and camera and accessories sales.

the name of the place is:

Marty's Camera Repair
71-25 Austin Street
Suite 203
Forest Hills, Queens 11375
(718) 793-4666

they've been in business for over 25 years.

Thanks for posting. I've used Chrysler camera repair which located on 34th Street across from B&H to have my camera sensors cleaned. They did a good job with my 10D but a mediocre job on my 5D(the 5D was really mucked up). The price to clean a full frame sensor is $70 which is a bit too much in my opinion.
