$375 sound about right for a TD05 16G rebuild?

Dr. Gonzo

It seems that I have some oil leaking out onto my garage floor from the intake on my turbo. I called a place that's in the area and they want $375 for a rebuild which includes balancing and coating something or other. Does that sound about right? There aren't many places in the area that will do the work so I don't have a lot to go by. I thought about buying the parts and having a stab at it myself, but not sure I want to risk screwing it up to save a couple hundred.
