So you've developed a product but have no prints, prototypes or even pictures? I can come up with my own wildly complex part, call it a gooseneck and your quote will be several thousand dollars for one.
If you think you have a viable product, you need to take this a little more seriously. If you don't know what to call it, make a name up and stick with it. Machinists don't car what something is called or what it does. Just supply a print and solid model and you'll get quotes.
If you don't have the ability to make prints/solid models, then THAT is the first RFQ you need to post.
And just so you know, you mentioned "cheap" twice, which means that several high quality shops have lost interest immediately.
