Yeah, I agree with what the other guys have said. I recently got a loaded pickguard from a company called HD Custom that sells their pickguards on Ebay and Reverb. Another company that does the same thing is Sigler; almost got one from them instead, but I'm happy with the HD Custom one.
I got a loaded pickguard because I don't particularly like soldering, and because when I totaled up the price of buying all the parts and a loaded, soldered pickguard was ~$20 more that buying all the pieces individually. If you were just changing pickups, and not the whole pickguard, that would be a whole different thing.
