I'm going to have to agree with Kirk on this one. To tell you the truth, the mechanical components and techniques of working on your own car are not that difficult. All you have to do is to have a basic understanding of what you are doing, what the torque specs are, the procedure for doing it, and the tools to do it. If you have all these prerequisites you should be more than capable of doing anything to your car. In the process, you might learn something and by doing so become better acquainted with how your car runs and operates and it will save you that expensive hourly labor bill that those shady mechanics charge.

In this day and age, if you do not have a decent paying job or income, I would not recommend letting any mechanic do modifications to your car, since you have no idea how it was done and if there were any corners taken to complete the task. This could cost you twice as much down the road, when something fails or goes awry.

I learned this fact along time ago. I've never been satisfied with any mechanic doing anything to my car unless I was present working on the car as well. As such, I now work on my own car, so I have nobody to blame, but myself, and I know exactly what was done to the car. Sure it may take longer for you to do something than a certified mechanic, but that's the essence of being in this hobby. To be a true automobile enthusiast, doesn't just include sitting in that driver seat and mashing some gears. You need to learn the ins and outs of your machine. There is no better satisfaction when you've done something to your car, by yourself, that puts a smile on your face when you take it for a spin. That is the essence of this hobby.
