I would not pay anyone, but expect to spend about 1hr on each seat...I know that sounds like alot of they can be a ***** to get the bolts to line up right...
Tip, Slide the seat all the way back...And make sure it is straight back, you will see that you can slide them unevenly when they are not bolted down...
Put the front ones in, but do not tighten all the way down until you have all the bolts in...
And not sure about your year but 4th gens have the sensor in the bottom of the seat for the fasten belt bulb, so check for anything connected to the seats before you yank them out
