Re: Print the legend
I'd find someone you trust that has done before what you want to do, but doesn't seem to want to steal ideas (or doesn't have the means to). Read small business/entrepreneur boards, and then reach out to someone. I help someone about once a month in your position, usually with one or more of the following:
CAD work
Finding machine shops
Sourcing from China
Ecommerce and shipping
Kickstarter advice
BOM review (DfC/DfM)
So far, I've only charged for the CAD work (hourly), as I like seeing people move things forward. If you're serious and think I can help, shoot me a PM. If not, look to find someone that is 1-2 steps ahead of you in a somewhat different field (so they are unmotivated to steal anything from you) and make it happen!
And if you're coming up with 2-3 ideas a day, roll the dice and trust someone. If they steal it, you have what, 600 more ideas a year?
