I would look closely at the recommendations of Ed Zimmer shared in this forum post
Basically, you should go research potential licensing partners and approach them with your idea, following the suggestions for the smart steps along the way as suggested by Ed.
In general, the Forums really supplement and add details to the inventing process. For new inventors, I always suggest they start with Myra's invention blog
and the other info on our Inventor Information pages
Good luck and it is good to have you on our site.
