The problem is, how much do you actually know about the local service you are trying to get?
Brake pads from a mechanic seems easy, but the person needs to know they only need brake pads. Most people would need to go to a mechanic to tell them they need break pads, maybe they just need their brakes bled, or they have caliper issues.
What's another 'local service' example? Physiotherapy? Is price really the factor you want to decide on?
I'm thinking about the businesses that are local to me which are service oriented (because just e-commerce already has this problem solved).
You'd think plumbing and such would fall into this well, but Angie's List seems to have solved that problem for most home goods.
What are the other goods we own that need local servicing? Computers repair, maybe, but people just go to GeekSquad or whatever else they can find.
I think there are some huge issues in properly defining the market and then understanding the customers your solution might fit, or figuring out how you can solve the issue for the customer, as that is probably the bigger challenge.
Great domain name btw!
