Fiddy: Great, here's a photo of me and I'll send you a few zesty rhymes about being the best.
Greene: Cool, we'll profit share and you can read the final draft before it goes to print.
Fiddy: Word. Split it into 50 chapters.

I saw a Hugh Hefner self-help column once: don't even know if Hef even knew about it. Here it is: http://tr.im/z3yQ
e.g. 'help' losing weight suggests things like a gym partner, a personal trainer, surgery, your spouse adopting your meal goals, etc.
'self-help' losing weight would be things that fall short of that: a workout schedule, a diet plan, etc. Things that have pointed you in the right direction, but don't include other people directly helping you.
What you're describing sounds closer to 'self-made'. As there was no assistance from anyone else, of any kind, it doesn't seem useful to include the word 'help' at all.
