Cam install
Normal labor if probally 400-500 on a cam swap alone as it is a dime consuming job.
then add 50 bucks if you do a timing belt, and maybe another 100 bucks if you add springs for the cam.
Plus 500 for tuning.
If you have the funds for the heads go for it. Maybe an additional 300-500 to swap the heads at the same time.

it's not that hard as long as you can set aside time. Don't rush things, that's when you have problems. Make sure you have a few days to work on it. You'll get tired and frustrated at times and that's when you need to go to bed or quit. Otherwise you'll do crappy work and reap the consequences later.
