Someone on Sevenstring.org has one of their 7's, he likes it a lot. I don't have any experience with them myself though.
most places like this you just have to call.
remember, if you have an expensive custom shop, you're going to get a ton of "LOLZ CAN I HAZ $300 GITURRR HURR DURR" emails all day. just call them.
edit- they have a ****ing ebony guitar? i like this place.
