Low production strategy

Hii..

Has anybody (reading this) benefited from using any of the low-volume injection molding services? I wonder what's the best way to take advantage of them. How do you strategics for your marketing, quality control, and most important of all, PROFIT? For example, my product can be made mostly of plastic. There's a metal hardware piece and some LED electronics. But not counting the electronics, the total estimates for low-volume runs come to 14k for 20 units, 18k for 200 units, 55k for 2000. And these are not even "mass production" quality either. They require special tweaking to the CAD models because of their versatile molding machines. So surface textures, colors, and certain forms are very slightly off. There are limitations on what you can produce. Then if you look at my invention, it looks like it can be made in China for under $10 and retail for under $30! Do the math. What's a good strategy for profit?

Please help.

I didn't find the right solution from the Internet.
