brakes are EASY, 150$ for replacement of pads there is no way on a saturn....go to rockauto.com to check prices. are you doing all 4 wheels? or just the front? are the rears drum brakes? if your doing all 4 wheels need to know if the rear are drum or disc brakes(yes newer cars can still use drums in the rear) for the fronts pads should run 15-40$ for both sides.front+rear rotors about 15-25$ EACH. if your rear brakes are drum's then you just need brake shoes(drums dont need to be replaced or resurfaced nearly as much as rotors) brake shoes run 15-25$ for both sides however you need a tool to remove the springs. for the fronts you will need to rent a tool from autozone/advance auto it looks like a clamp but with GM brake calipers to push the caliper piston back in to fit the new pads it twist's in and out, some cars they just push in and can use a C clamp and a piece of wood. tool rental is free from most auto parts store's just require a deposit the price of the tool. best thing to do is google a place called "valore books" and search for the ISBN number of the chilton or haynes repair manual will show you how to replace most parts with ease....but rockauto.com is one of the best places i found to order parts. good luck with your brakes, imo dont use autozone or advanced save your money and use rock auto, sometimes you can get way better parts for the same price you would pay at the local big box auto stores....and a repair shop will make you bend over and take it, so id find a competent person to do your brakes that is mobile, or ask your friends if they know anyone good....i do all my own work, and replacing brakes are really easy if you have a simple set of tools(gm calipers require a big hex bit for removal) and are somewhat mechanically inclined. you could also post a craigslist add and see who responds just ask them questions you know any competent mechanic should know.
