There several advantages to rotating banners:

1) It allows pages they're displayed on to "look different" every time someone loads a page, giving your site a more "fresh" appearance.

2) You can display a variety of baners without adding more bandwidth to your pages or taking up their precious real estate.

3) If you participate in a variety of Affiliate Programs where you make a commision on sales, now you can rotate those banners they give you and possibly make more money at same time.

4) It's a known fact that after someone views same banner over and over they'll become immune to it, thereby reducing click thru rates. With rotation, they're always fresh.

5) If you want to sell banner advertising on your site you'll need some sort of banner rotation script to track click thrus and impressions for your clients.

The advantages are clear, so where do you go to get a script like this? There are a number of websites that offer them for free. All you need to do is download them and tweak a few lines of CGI Code. Try some of these more popular sites:

TIPS FOR YOUR WEB SITE If you are a "real" company with "real" products and "real" people, please put your address and phone number on your site (usually on a contact page is best). Afterall, you put your address and phone number in your city's phone book don't you? You put this information on your business card too, don't you? Think of your cyber presence same way you do with your earth presence. Most people will be more comfortable ordering from a company that doesn't appear to be hiding behind anonymity of internet. An address may not be as important as a phone number as some businesses are home businesses and safety concerns may be an issue.

Please let your visitors know right up front - before they fill out forms - that your offer is good only in USA (or wherever). As well, let your visitors know what currency your prices are in. This is especially important to Canadian visitors who are burdened with "dollar that isn't worth a dollar". And speaking of forms.... please check them to make sure they work properly. Make sure you have enough characters allotted to all fields so that user can correctly input a postal code or zip code, province or state etc. - And, if I spend a lot of time filling out your form, I expect SUBMIT button to work! If you are using java for your forms, please check that it is compatible for both Netscape and Explorer.
