Price seems reasonable. However, ask them to see some other cars that they've done to see the quality of work.
Also, check if they're dying the leather or spraying it. Sometimes spray work rubs off after a few months and you end up with the same problem.
Some places remove all the seats, take them apart as much as possible and do a proper job. Some places just leave them in the car and do a best effort on the corners, etc. Ask the guys how they intend doing your car.
Lastly, how about doing an intro with some pics of your ride :thumbs:
