So, nerd stores
Well, what about starting an engineering company? Well, there's issues there with getting a license, which requires working with already licensed engineers for a length of time, plus getting contacts for jobs, and starting something without a reputation or experience. So for the moment, that's not really looking practical.
Computers? Well, I know them, but I'm not a hardware guy, and I haven't kept up at all with programming languages, network stuff, or anything like that. So I could learn it, but I don't have any of the credentials or experience there.
Working for somebody else in retail sucks, especially in a crappy economy, which is where I'm currently stuck.
So, what kind of retail could I do? Well, the most obvious is a nerd shop, probably comics and games. I worked at a game store for five years, I've been friends with people who ran comic shops, I know both those markets pretty well anyway. And it'd give the possibility of creating a place for people to come and meet and have fun and interact, and that'd be good.
Comic/Game shops are hard, though. They're operating in a relatively small market, comics are non-returnable for little guys, and costs four bucks and up each. That aside, there's also a lot of stereotypes about comic and game shops, like they're essentially some dude's basement. And there really are ones like that. Or just look at The Ferrett's column about his FLGS. There is a comic shop chain here in Savannah, but as their webpage shows, they have a bit of hoarder in them too. Plus there's nothing else to that site besides that page. But the pictures, with the T-Shirts hanging from the ceiling and the confusion, that's not so appealing. The hobby shop I worked in had some of that too. We kept it mostly clean, but it was piled with stuff, especially trains, almost to the ceiling on a lot of shelves. So, obviously, I wouldn't want to do something like that. Running somewhere clean, safe, and welcoming to everybody would be the goal. There's no point in turning away customers by having the store look bad.
The problem there, even in a city like Savannah, with SCAD having its art college with a sequential art series, the market for comics isn't always that big. and the comics don't always help with that. And that's a little scary when looking at opening a shop. Comic stores are always shoestring businesses, which is part of the reason so many end up messy. There's lots of other things out there, and there's lots of TPBs and the like that provide more value for the money, but I'm not sure how easy it would be to try and change all of that. Or if I'd make any money doing it, and not just end up owing even more money when it failed.
