How much does it cost to fix oil pan and drain plug?

I got a 1996 Toyota camry. I went to another place for an oil change and they found oil pan threads is pulled and drain plug threads is stripped. They suggested me to bring my car to a repair shop as soon as possible and also they said whoever did the oil change last time is the one responible for those damaged. However, I already moved to another town and it seems little impossible to ask for warranty because I can't bring it to the last shop to fix it. So I decide to bring my car to another repair shop to fix the problem.

Find out size of drain hole and buy a retreading kit. I also would buy a plug that has a lever on the end so when u screw it in there u push lever down it has a rubber seal in it. When u push the lever it spreads the rubber out to fit more snugly. I can remember what those plugs are called though. I used that kit and it worked.
If the pan and plug threads were stripped already, was the car leaking oil there? It seems more likely they were fine and the place you took your car to this time, not last time, is to blame for the stripped threads.
