[@TheUnknowable]: Let's see what I can say in the time it takes me to finish this subway ride.

1. Well, I guess you've made a way. Kind of.
2. But it's not as if he'd get paid for that, though. A job like that isn't exactly something to be publicized.
3. I'll fish out SOME tech store idk. Or you could have him just... Buy the parts outright. I dunno. Not as important rn.
4. Tech startups are about it, afaik, but it's not like I can't google tech firms later.

He'll find a way to make money or another (as will... Probably everyone else).

As for the whole suit thing... Yes and no?
While the suit is functional, it is a) not reproducible and b) people still don't know the safety of the stuff he gives. He could probably make easy bank just by coding, though, so we could just scrap that subplot and not have people freak about new tech.

(Also don't forget that the suit is a weapon system, and honestly with his reputation and mind all he needs to do is put a few programs of some sort out on the market.)

Doing that solves the issue of trying to sell tech in the first place, and it's a lot easier to handwave something like a program because NONE of us are going to be staring at source code for this RP to make sure it works.
