Afaik, this is a DIY project, so unless a company wants to pre-assemble boards, you won't find one. I have experience soldering, and will be making spare boards, but not right now, since I have other projects pending before this one. When the boards are available, I'll let you guys now, but bear in mind that I will probably start around March or April, and that I'm a hobbyist, not a store... 😀
