Designing it isn't the same as "Getting a Chinese Manufacturer".
Tell me about what it is you're thinking of, as right now I don't know if you wanna make a freaking car (which I couldn't help you with), or if you've got some idea for some little electronic device (Mass Production, woo!!!).
DK, I have to say that I love your avatar and it never stops making me
Anyway.....I have taken 2 college level engineering courses and will major in EE or computer science and Engineering next year. So I'm curious what your idea is. You can PM me if you want. I won't steal the idea (I have some ideas of my own that I am too focused on)
