You also need to figure out a niche' to sell in. With all of the inexpensive vinyl cutters out there anymore, there is a lot of competition. You have to stand out to sell anything. You don't want to be selling what everyone else is selling, or you will be just fighting on who is selling the lowest price. And you will not make any money doing that. I set my prices and I don't care what others are selling at. Or making 6" "stickers" won't keep you in business. It takes more time to do that kind of work then to make big vinyl graphics. You have to find a niche' that works.
