Labor would be quite a bit from a shop. Do both the cam and crank seals (they are the same). I hope you're also planning on getting a new timing belt, tensioner, and possibly water pump since you're in there. When was the last time any of these were replaced?
Setting the cam-crank timing is nothing to worry about. After you put the belt back on and tension it, turn the engine over by hand a couple revolutions and verify that you lined the marks up correctly.
