RE: Having locals do the routing
Be careful. There are a lot of self-proclaimed experts out there.
For example, I recently picked up a used
ESP M-III with a floating Floyd bridge at a local shop. In the process, I asked the shop guy about the best guitar tech in the area. After mentioning an independent tech, the guy also mentioned that their tech is excellent.
While discussing the tech, I started checking the setup of the ESP. It turned out the tech had adjusted the tension on the _floating_ bridge to the point where the bridge was abutting the body. Therefore the bridge was no longer floating. Such a setup creates numerous problems, including at least:
1) The micro tuning pegs press against the body, thus adverseley affecting the entire tuning of the guitar when one string is adjusted.
2) The bridge is at an improper angle, thus creating intonation problems.
3) The bridge is at an improper height, thus creating dead spots on the neck.
I had to personally extensively adjust the bridge height, bridge angle, and spring tension before I was happy with the setup and willing to purchase the guitar.
Point being, if you do enough research and are confident in your abilities, you might do a better job than the local tech. Of course, since this is your first experience with such a setup, you may also damage the guitar. Your decision on how to approach this situation may depend on your willingness to damage the guitar and chalk it up to education and experience.
Be that as it may, this isn't nuclear engineering, it's guitar teching. Most competent people with a little education should be able to build and/or modify a guitar without damaging it.
