Mike if you want to get your hands dirty and learn stuff I would do what jeremy did, that's the option I will be taking.
That way the machine shop will be doing all the precise work and you can assemble the easy stuff.
Also I wouldn't bother documenting, Jafro has done an amazing job and documenting all his builds and video does a far better job than writing and is far more efficient too.

I will however send you a spreadsheet I have that give you what internal components are recommended for each power goal.
