in my 30 odd years of living, i never had a pair of shoes repared
i didnt even know it was possible to have a pair of shoes repaired. Shoes are fairly cheap nowadays, coming from China and low cost countries. People often buy new shoes long before old shoes need repair.
In your town of 3300 people, how many people would use a shoe repair service if there was one? It might work, but you need to do your homework before you start your business.
