Talk about beating a dead horse....
A search will yield you many results as to the "custom shop" issue.
Bottom Line: Bottom line. It's just plain not cost-effective to open a custom shop. Sure, you'd be first in line, and a dozen others, but what about after that? When costs aren't covered, things go bye-bye.
If you *really* want a custom Ibanez guitar, talk to any of the sponsors of this Forum, or check the Vendor list. There are a bunch of good folks with much talent.
For those quick to bitch about options not being available, take a look at the Gibs*n and Fend*r catalogs. If I remember correctly, the 2001 Gibs*n catalog offered EIGHT different guitars and two different basses. That's it. Last time I checked, Ibanez had over 20 different models coming to the US, many with at least 2 different paint or finish colors on them.
The options are there, you just have to take a step back and look at the broader picture.
