You'd need to decide which pickup you wanted first, and you could probably do it yourself. All you need to do is solder a few wires together. Failing that, your parents might be able to do it if you trust them with your guitar.
A dwarf might hear you. What then?

Youd have to ask around where you live, because every repairman is different. I Replaced my Pickup and it took me a few minutes...just make sure you get a book and some advice or help when you do
