Spend some $ on a tool kit for your bass. Allen wrenches (metric and standard. Be prepared!), a feeler-gauge (auto parts store), and a small assortment of screwdrivers. This will cost you less than half of what you would spend on a setup. Then learn to do your own setups. The "setups" sticky in this forum will help you a lot.
Acquire the right tools, and gain the proper knowledge. Its not hard.
