One solution is to continue trying; Another is to "sell out" to BigCo;

Yet another is to publish your idea and possibly get hero status when someone that understands the relevance of your idea and has the necessary resources/skills to make it happen does so. You'd probably feel good about those 6 years spent thinking about it and researching it not being completely in vain.

I'm a bit freaked out thinking that great ideas can die with their originator if they never publish...
