You all still need to eat. Have you put together even a simple profit and loss model to estimate what your operating expenses will look like (e.g., rent, insurance, supplies, your salaries, utilities, etc). On top of that, you're going to have some up front costs such as initial stockage, displays and racks, tables, signage, etc. If nothing else, you and your two buddies need to sit down and have an honest discussion about what this is going to take to get it off the ground.
Also, be honest about your motivations. Is this a true opportunity to make a living or is this really an avenue for the 3 of you to get miniatures cheaper. I've seen too many hobbyists get into the business for that very reason, and end up running a store that caters to themselves and their friends only, and ultimately fail.
