Not to put dampner on things but the idea of running a record shop for most is (I'd wager) a bit of a fantasy that you can make a living sitting around listening to music all day. If you're running it right you won't have all that much time during the day to enjoy listening to music cos you'll be too busy with the day to day, full-on job of running a business to indulge in (perhaps) the reason why you wanted to run a record shop: out of a love of the music (and maybe the idea of listening to music all day). If you can combine a hobby and treat it as a business then you're doing well. Not only have you got the financial side to keep in order but actually managing large stock levels is a full time job. Seriously, having worked for Soul Brother for 7 years + you see how shrunken the UK market is for soul stores - the internet has undoubtedly played a huge part in this, but also people's listening habits have changed. If you think there's a big enough walk-in market in the area you're looking at setting up in then maybe it'll work but you also have to pitch your stock to accomodate a range of soul styles that reflect not only your taste (and possibly not your taste) but those of potential customers. So that'll include smooth jazz and urban, then I wouldn't envy anyone setting up a specialist bricks 'n Mortar store in this day and age, and even trying to compete on the net as a newcomer has to be daunting, particularly in terms of new product. If you've got a huge and endless supply of rare, collectable and in-demand titles at competitive prices then yeah, maybe a net shop is the thing, but when Tesco or asda can stock a soul comp at 30% less than an indie store, be paid for racking space and have a larger returns privellige you know it's tough! Ebay and Gemm (especially) etc have made everyone a potential record dealer, also. Not sure how you'd tie in food and records...seems like you'd need to employ double the staff and logistically it's a bit of a leap of the imagination to figure out how the two would combine.
Good luck though
