How much is it to start a comic store?

Me and my friends just were wondering how much it is to start and run a comic book store.

I wish I could give you a number, but there are to many variables to consider.

Rent:
You will have to lease a place. how much square footage will you need? In california you are looking at $1-4 per square foot depending on location. You will need first, last and a security deposit.

Inventory:
You can start with your collection, but think about how much that really is. Most collectors do not have the volume that a store needs. we tend to collect one per issue, and not duplicate in graphic novels. Stores need alternate sources of revenue other than comics. You can purchase collections to make up your back issue bins, but you will still need graphic novels, toys etc. What else will you be carrying to interest collectors: (here is a pic to get you thinking)

fixtures:
you will need comic racks and glass cases, a cash register and a security subscription. (overnight monitoring, lotsa break ins) wall racks and comic book supplies to make your collection sellable.

Initial comic order:
how many of each current comic will you be carrying? Diamond has minimum monthly order requirements. Im pretty sure you can sell the minimum of New Avengers, but how will you decide on the order for loners or nightwing? remember each mistake is close to 2 buckswholesale of unsold merch.

It certainly is a tough business, but some do succeed. If you are serious be ready to put in long hours.
