Banner Design

I need 4 banners designed for our websites that illustrate the benefits to booking taxis on-line.

Banners most have strong calls to action and encourage people to book on our website.

We would like screen shots of the website to be used and we will provide the text we would like to use.

An example website can be found here
http://www.retfordtaxis.co.uk/
http://www.chobhamtaxis.co.uk/
