That's why you should start a kickstarter-project. Chance you will probably gain attention. The ones that are funding (most), will receive their board first or with special option (color?).
You can set the bar to a certain amount of money, so you can buy a injection mould (spuitgietmatrijs for dutch).
After that you can start producing for a lot less. You can think about making the injection mould for both plastic parts at the same time
