If I had a idea for propellant-less propulsion who would I contact to evaluate it?

Prior physics student with lots of book knowledge but total newb when it comes to actually finding investors and making things happen. That and my severe lack of a social life. I know a little bit from what I have read about non-disclosure agreements and patenting but don't have much financial leverage. I am some what convinced (but still want to test it to be sure), that the idea should work. However, it requires the right tools and equipment, but I believe I know exactly what to do. There should be some one out there interested in this sort of thing I would think. After a while of thinking about it and scouting NASA to see what they have and running into what seemed like multiple dead ends I thought maybe I would just ask here. Any ideas? Thanks in advance.
