I hate to be one of "those guys", but you really need to learn how to do it yourself in this case.
I've owned six Ibby SRs, and every one of them required setup adjustments every couple of months, no less than 4 times a year, in order for them to be the way I liked them. Liked.
It's relatively simple if the bass isn't completely out of whack, a slight tightening of the TR when it was cooler, looser when warmer, some saddle adjustment here and there. You'll save yourself money and the headache of dropping your bass off every other week.
