What do you think of my idea?

I’ve been working on a project that is nearly ready and I wanted to get some feedback on it.

The site will allow businesses to post videos of their products or services. Each business will have their own profile page where they can provide info of their business and display their videos. Our site will be for businesses that sell everyday items such as electronics or services like accounting. Visitors will search the product they want or search the name of a business and get a list of results. They will be able to browse through the results and watch product or service demos before they buy. We think of it as a culmination of YouTube, Amazon and Yelp.

I would really like to hear what you think of it and more importantly would you use it?

Replies much appreciated.
