How can a fishing gear product be sold to the national market?

If you have confidence in your products, and they are really easy to use and cheap, I feel that you should stop thinking about occupying the national market. You should first occupy the market near you or the regional market, find a bigger dealer or a bigger specialty store, discuss cooperation with their bosses, promote your products first, and have a good strategy, otherwise how can others sell your new products? If you have a well-known influence in an area, I'm afraid it won't be popular in the future. Establish a brand first.
