This is all good, but you're making a mistake I see many people make: If one person has this experience/questions (me), then many of your other visitors will. Answering here will answer my questions, but it won't answer everyone else's questions.

My recommendation would be to have a clear "see a demo" button, which leads to a website that showcases the most common elements I might want to have on such a page (a form, some graphs, etc), maybe with source code close by.
