Affiliate Marketing Secrets

I have several inventions (some designs, some prototyped) that have a lot of potential (I’m not some moron who’s inventing snuggy pt.II I’m actually an engineer with an ok business background so I’ve vetted my “sellable” ideas and ditched the “will never make it” pipe dreams.
Unfortunately I have a full time job and can’t afford to “walk away and persue my inventor dream” I have too many responsibilities that are tied to my paycheck. It seems all the web pages/literature (even the experts at Eureka Ranch) basically say “If you don’t do it yourself you’ll never make any money” A concept that I find impossible to believe.
Is there a company that will vett my idea, and if it passes first round then just take the lion’s share of any money that comes from it? I’d be happy with 10-20% of revenue and Name recognition (some of my inventions for the disabled I’d just settle for name recognition)
Every single “Inventors/Invention” company I’ve looked at is a scam, they’re all companies that just want to sell you a boilerplate portfolio and/or different levels of patenting.
I’ve watched about 10 ideas that I’ve had over the course of the last 7 years turn into money makers for someone else (I have poor man’s patents but a lawyer will laugh at those, I only did that in order to have proof of my ability. So surely this can’t be the only niche in the world where there’s not a company ready and willing to exploit me and my ability to make more money for themselves?
Any help, pointers, links?
