Title: How does one go from an idea to a sellable product?<p>I have various ideas, not especially &quot;high tech&quot; more assembling of off the shelf components to create novel products that I think may be useful (I have a need for these myself). So I could build a prototype myself (despite being a software person). After that what? How do you find out about manufacturing costs and options? Marketing is another side, but I have an idea about that.<p>Are there any good guides out there?
