Best advice is to call a local repair shop. They can give you realistic prices. Pots and jacks are relatively cheap...no more than 5-8 bucks or so, pickups range widely in price. Then tack labor price on top of that unless you no how to use a soldering iron and have wiring experience. As far as paint jobs go...I would leave it alone unless you know specifically of a local shop that actually paints guitars. For instance...don't take it to Maacco! Good luck.
