This is common to mechanics, so you better get used to giving them a stock answer. You should have two in your arsenal - "No, I don't do side jobs" for people with problems you don't want to deal with, and "I can fix it, you'll have to pay for it, but I can cut you a deal".

From there, I'd make sure I bought the parts for them - if they get cheap-ass parts, they'll expect you to fix it again and again.
