If you're confident with you building skills, you just need to get a reputation, some recognition, and credibility.
I was fortunate enough to get into Destroy all Guitar pretty early on. That got me the recognition and especially the credibility. Reputation takes time and can be frustrating. A lot of people won't review your guitars or get them seen publicly, but that's really the only way to get it. You just have to keep at it and do your best to blow minds.
The longer I do this, the more I realize that standing out is key. I've known builders who make great stuff, but can't sell anything because people can easily go with somebody else with a longer reputation or a cheaper price. If you make guitars that nobody else is making, they'll sell much easier. People need to know that if they want something like what you're making, they have to get it from you.
The more established builders can make stuff that's more traditional and get by because they have a recognizable name a long reputation. Newer builders cannot do the same thing and compete. Demand is extremely important, but if they can get something similar from somewhere else, it won't matter.
Look at any of the newer or younger builders on DAG. Everybody is making stuff you can't get anywhere else. I don't just mean visually, either. Even guys making Strats and Teles like Red Rocket are making them so unique and beautiful that if you want something like their guitars, you have to get one of their guitars.
