So I've started drafting the very beginnings of a business plan for a Less Wrong (book) store-ish type thingy. If anybody else is already working on something like this and is advanced enough that I should not spend my time on this mini-project, please reply to this comment or PM me. However, I would rather not be inundated with ideas as to how to operate such a store yet: I may make a Less Wrong post in the future to gather ideas. Thanks!
