Pricing this job on a forum accurately is difficult there are just too many variables. The labor could be anything from an hour and $100 for the OE shoes if everything fell apart and that is all that was needed for parts. On a 13 year old car living in an area that uses road salt all winter that IMO may be getting a bit too optimistic in reality the drums may be a bugger to remove and shot, the springs should be replaced, there is a chance the backing plate is rotten and the wheel cylinders are shot. Have I said anything about the parking brake system yet?
Removing the wheel cylinders may damage a brake line and doing the backing plate on some cars requires removing the hub which can be another can of worms. Been there done that many times over the years, a small insignificant job in low rust areas turns into a real (and expensive fiasco) in the rust belt. Use OE drums and parts if needed aftermarket drums in general suck bad and don't bother turning them, there are very few people left that can do that job or maintain the machine properly.
I am not saying this is what is going to happen in this case but be aware it easily could, forewarned is forearmed.
