Even if you don't have mechanical skills you could easily change the front, passenger side or trans mount yourself. They are all that simple. The rear takes a bit of craftiness to get at and swap out.
But your going to pay whatever the shop's labor rate is and even though the front can be swapped out in 10 minutes or less they will charge the full hour for that. Find a shop with a lower labor rate and have them do the rear only and do the front yourself if you can.
