Best way to get a new pickup routing....

Hey guys,

I want to convert an HSS routed guitar to an HxH routed guitar. The thing is, I don't have the expertize to do it myself, nor would I wanna take my chances.

So I was wondering if you guys can tell me the best way to go about this problem. I mean should I contact my local music stores and get a quote from them or are the luthiers the best way to go around it? Whatever the case, where do I find these sources? I mean I tried searching for luthiers in the yellow pages in my area and it found nothing. Also, the only music stores I have near me is a Sam Ash and another local music store. Should I give these guys a call?

One last thing, what would be some of the issues that I might have to deal with in this transition? I mean does the new routing hurt the finish/needs refinishing? What kind of pickup switches are going to be needed? And finally how much extra would it cost me to add a coil tap in the neck?

I know I could find a lot of these answers by calling some people, but to avoid being over charged and having some info before calling, I decided to post here to get some knowledge/opinions. Thank you for reading.

P.S: What does it mean by F-spacing and direct mounting and non-direct mounting, and how do these things affect the tone and installation of new pickups?
