First, I applaud your enthusiasm, and for not responding in kind to some of the negativity in the comments. While I'm sure that there are a few who are just negative, most of the people offering criticism probably genuinely want to help. You'd be wise to listen to them. And in the spirit of offering advice, here's my two cents: read "Four Steps to the Epiphany" and actually follow the advice. If that's too much, then just call or email 100 potential customers, outline your idea, and ask them what they think. These should be real potential customers who you envision would really want your service, not friends who once sold a piece of furniture on Craigslist. I can tell that you've got some emotional attachment to your idea, so this step might be hard, because you could find after 10 or 20 calls that things aren't quite the same from your customer's experience as you thought. But just keep going. By the time you have talked to 100 potential customers, you'll know exactly what they need, what they don't need, how they find new products, how to market to them, etc. Good luck, and please do keep us posted with your progress :)
