how easy is it to degree cams

I have been reading a lot about degreeing cams. How easy is it to do this? I have never done it before. Does anyone have good write ups on this? How much would a machine shop charge? I have looked at summit and saw them for like 90-140 bucks.

I wondering if this is my problem because I have ptv contact.

Thanks.
