Question

need info of where i can go to produce prototype.

Answer 1

\Do you have a design on paper?
If not you need to start with that.
You may be able to find a design company that can help.
If you have a decent design then the best bet is to learn how to sew and build the prototype yourself.
Otherwise find someone that you trust to sew it for you.
