Lol, I'm actually signed up to run with this guy tomorrow. I thought it was cool he's extending an open invitation, I thought I'd put my name down and see if he had any interesting tricks to supplement my own knowledge (also, the scrub that I am, I still don't know where most of the less-obvious Crota chests are, so if nothing else, maybe he can help me with that :3) But yeah! There are tons of people like this guy, although most are not nearly as well-organized. If you visit the forums regularly, it should become clear that there are plenty of people offering up their 'coaching services', you just have to look for it :)
