Well, there are a lot of factors. You are asking us what we as comic readers are looking for. Which is cool. However, you also need to think about yourselves as investors, considering it's your money you will be putting into the business.
Location is going to mean everything. How easy is it to get to? That means a lot to me. There was a shop that I loved going to about 15 to 20 years ago but it was SO HARD to get to it because there was never any decent parking near it. My mom would drop me off and keep driving around the block, haha.
It depends on how much money you have at your disposal but if you want a GREAT location try to open your store in a busy shopping mall. You will do KILLER business in a mall.
I live in Pittsburgh and two out of the five comic shops around the town are in malls and they do great business. They get TONS of walk ins and lots of kids who get drug there with their moms.
I saw another poster mention it and I will back it up....sell other things besides comic books and graphic novels, etc. Get into the Role Play Games and card games and Pokemon, Yugi Oh, or whatever. Action figures. You want to try and hit EVERYTHING in geek culture.
Also...when you are going to hire people to work in your shop, make damn sure you are hiring trust worthy people. The one shop I frequent hired a real *****e bag recently and he lets his friends hang out in the shop and read the comics for free. That's a no-no. You want the guy who has his friends hang out there and makes his no good friends buy the comics! Haha. Try not to hire the holier than thou comic book guy. Having a guy who puts people down for the comics they buy can be bad for business. There is a store here in Pittsburgh where there is a guy that has to CONSTANTLY make some back handed comment to people when he's ringing them up.
I have been going to one comic shop regularly for about 10 years now. I go there because the owner is a great guy. He has a great subscription system and, due to that, he makes sure he gets to know you as a customer. That way when you walk in the store you are not feeling like an outsider. He welcomes everyone and he's very knowledgeable about the creative and business side of comics.
Also...it doesn't hurt to hire a good looking girl. That always gets guys to come in and spend money.
