Do what you feel comfortable with yourself and specify what you want them to do
For example a full first service on my Triumph was $380. plus oil and filter, but all I wanted them to do was check the valves, I do everything else myself. It becomes a straight hourly rate job, 2 hours @ $80 p/h=$160.
With my failing short-range vision and clumsy hands it would take me all day, so it's not worth it to do that job myself. Everything else is cake so I do it myself and get to know my bike in the process.
Don't get talked into biting off more than you can chew.
