Owning a book store

Personally, I would start in cyberspace. Make a virtual store first. The rent is a lot less. Typically less than $50/month including credit card processing through paypal or something. Once you have some income from that leverage that toward a brick and mortar store and use the success of your on-lien store to help when you apply for a loan for your business. If you can prove the concept is successful on-line you'll have a better chance with a lender.

Oh what a lovely idea, I think this is such a good idea that if maybe just letting it known out there and I mean really putting your idea out there maybe some already successful artist can see the benefit for the up and coming artists, someone may come along and give you a bit of help to start the whole thing off, here in Australia we have local papers that are community based and people are always getting help just because someone thinks it is a good idea and want to help in some way...I sort of do a little of helping to different country music artists here in Melbourne, by putting a page for them on my webpage for them, as I have a page for a rather high profiled person, there are always people out there willing to help a good idea..Good luck...
