What to charge for Videos

In small towns (25,000 or less pop) I've noticed not many restaurants have websites.

And, with Video being "Hot" right now, here's what I'd like to do;

1) Set up a website Directory for a town
(ex: MyTownsBestRestaurants.com)
2) Go to a restaurant and tell owner I'd like to make a Video of his restaurant showing photos of the outside, inside and plates of food at NO OBLIGATION. If he likes the Video, we can discuss cost, later.
3) Take photos with digital and make video with PhotoStory or Muvee or Movie Maker and create a DVD.
4) Purchase portable DVD Player (Phillips at WallMart for $80) and go to restaurant and show owner my video.

5) I would place the video on my website in the proper category for his food (Family Dining, Chinese, Mexican etc) and promote the site locally (Newspaper, Radio, Google Maps and whatever else I can think of)

Now....these would be 60 to 90 sec videos with appropriate background music and text. I'd make a "Video Skin" for each restaurant with address, phone, description, hours, etc

Now....WHAT should I charge for this?
1) Initially?
2) Monthly?

If anyone has any experience with this or knows of someone who's done this, it'd be much appreciated.

Thank you,
