From listening to all your questions tonight, I came to understand that a few people may have specific questions that we may be able to help with. Which is why I wanted to direct you to our Blog, http://smithherrick.wordpress.com. So far we have covered 5 topics and update it once every week or two. This will give you all a good base to work from.
1) How do I get my product idea from a napkin sketch to the buyers hands? 2)What are the steps in a typical product development project? 3)What to Look for in a Good Product Design 4)Why is the Manufacturing Method so Important and How to Choose the Best Method 5)How do I Get a Prototype Made and Why do I Need One?
There is some great information in there and I hope that it helps.
