I have the idea of the century!

it is worth a million $$$ !!! But I need to make a prototype of it in plastic, similar to the plastic that paint buckets are made of. In fact, the product is about the size of a paint bucket.

I have looked around and I have inquired of a couple of modeling/prototype companies but I am am leery of sending them my idea while I have not submitted for a patent.

I am certain that this idea is a WINNER. I am looking into the patent process so any help in that regard would also be very appreciated.

Thanks in a advance!
