... all I am saying is sit down and do the sums and be realistic. If it were that easy, then there would not be a shop for you to rent and Julian Greaves would still be trading there.
Nevetheless, it is still better to have tried and failed than to never have tried at all (unless of course the cost of trying was losing your home!!).
It's got to be worth a gamble. A smallish market-stall sized affair isn't going to give the same scope for displaying and storing stock as an actual shop and the latter ought to give customers a better picture of what you're able to offer them (as well as doing it in a more eye-catching way with the extra space available) - hope you manage to make a good go of it, keep us posted as to progress!
Koupe might have a point, too - independent local stores seem to be faring better than big to medium sized chains in this neck of the woods at present. Going down the eclectic/quirky route could well pay dividends.
P.S. I momentarily mis-read "the footfall isn't bad" as "the football isn't bad", even though the Posh are having an even worse time of it than Wolves at present....
