buy the design from people like orhadar or crazyfranky, get it printed through fabric on demand, get it sewn through trophywife, get the faceshell and lenses through tjack. if you're on a budget, getting it printed and sewn through herostime is good too.
You should try zentai-zentai.com. Everyone here HATES this site because they used to steal orhadar's patterns and use them to sell suits without his permission. However, because of all the hate, they have stopped stealing designs andyou now must directly buy the pattern from orhadar(or anyone else) and send it to them before they'll make a custom suit. Suits that feature orhadar's designs on zentaizentai have a link to his site so you can buy the pattern and then return to the zentazentai site to place an order. It's pretty cheap!
