Can you remove the wheels, maybe one at a time, take them to the shop and then reinstall them? That'll save a lot. The rate here for carried-in wheels is $20.
Amen, brother. Been doing my own tire changes and balancing since my second bike back in 1978. In fact I do all my own work.I don't mean to harp on this but it would benefit you to learn to do this job at home--you save lots of money doing it yourself and it makes you way more secure in handling a tire problem out on the road.
I do all my own tire changes and have helped all my friends with their tire changes, and if you make a party out of it it is even fun! Someone can bring drinks and get some music goin and its fun messing with the bikes with friends. I would rather do a perfect job of it for myself than hire someone else to do it. I always get a perfect balance at home--very satisfying.
