We have a fellow that does that with tires at peoples homes, and We also have people that sharpen knives and scissors ans lawn mower blades etc and homes at offices.
I would just do it. If the town catches up with you it is no big deal they will tell you how to go about it. My daughter did that in several area with a hot dog stand. There were approached in some towns and not in others. There were just told the laws, no big deal.
I would go to fairs and farmers markets. Just sitting in your shop will not get the word out. Make sure you bring your cards and get a web site up to sell on line or free delivery over a certain amount of money. Make a delivery route and stick to it or charge for delivery.
