Not sure what a Dealer charges of a tune up...this should be plugs and possibly wires. Get an estimate. You could then find a good mechanic and compare prices.
One thing...just changing the timing belt is probably not enough. Normally you should change the 3 idlers, tensioner, and water pump. I doubt that was done at the required interval of 105K miles.
