You get what you pay for, Jim.

I know the upholstery game pretty well, considering, and for $100/seat - you're lucky to get them removed from the car and pay for the materials to reupholster them. Maybe in some shitty cloth that will wear out in about 12-16 months in the FL sun/heat. High end vinyl (leatherette's) or leather is going to run you some coin.

I've got a guy in Brooksville, but it's gonna be around $500-750 depending on what you want done & how fast.
