Howdy Skout, welcome. They are great fun to sell. I would suggest start out small and just do a few. That way you know how long it takes you to build one on average. (I am slow as dirt, lol) How much you you need to make and what the local market will bare. Later when you want to expand, you can look for a wholesale supplier. Side note, the internet is gonna have a good many folks selling by spring and for every 100 ppl who want one, maybe one will actually buy. It is a great side line thing. Best of luck!
