Thanks for the suggestions! For this first attempt, I'm going more as a marketing exercise. I want to walk before I run, so I can make the mistakes with a proven product. After I learn the ropes a bit, I have LOTS and LOTS of ideas to try.
Finding buyers before production of interesting products is a dream come true!
Anyone have experience with Kickstarter or Indiegogo? I think those are the two best known, and GoFundMe seems to have a much different audience.
