I believe most shops charge a flat hourly rate because it is a customization that will vary by car and customer. Most people do it themselves, but I wouldn't suggest it unless you have a thorough knowledge of your wiring in your car. You risk damaging important wires & components and/or cause it to catch on fire if not done properly. Both of those end results means you're at the shop paying a flat hourly rate to repair the damage plus the tow bill to get it there.
Call around to local car stereo installers, some detailing shops, or any shop that does custom work. Get a quote, but don't stop there. There are a lot of people that say they can do it, but have only a basic understanding, maybe slightly more than you. They charge you $30-$50 and promise it back to you in an hour. Be leery of those deals because the installations usually end up being broken clutter under your car or laying in the street somewhere within a month or two.
I just finished installing an underbody light kit on a Suzuki Hayabusa. To do it correctly, I had to partially disassemble the bike. I also had to uninstall what was left of the previous kit (installed the previous year by the owner), repair the damaged wiring, and then install the new light kit. When I finished 8 hours later, everything looked like it came from the factory. Total bill, I gave him a deal at $400. The customer supplied the lights and saved a ton on the short term ($35 online). Normally this customization is in the $500-$600 range and the lights will last much longer.

The cost greatly depends on the company and the type and size of hot tub you would like to have installed.
