Banner Ad needed for company that creates adverts using water

We wish to advertise on a website and need a banner advert designing in JPeg format to sell our water cleaned advertising services.

Accepted File Formats:
Standard Web Formats (.jpg, .gif or .png)

The banner needs to be 160x 600 in jpeg format. Our company is http://www.streetadvertisingservices.com and we want a banner advert that portrays one of the adverts we can produce for customers. Check out our website for more information on what we do, feel free to use any pics on the site to assist you in building the banner. I'm thinking of an advert that looks like one of our street advertising designs with somebodies barefeet next to saying, 'We place your products at your customers feet'.... I'm really open to ideas though and have no specifics around typeface, style, colours etc. You guys are the imaginative ones!

You may see from my previous contests, im quick with feedback and will make a prompt decision when i see one I like, so the contest is unlikely to run its full course. I'm also open to discussing a complete website re-design with the winner as our existing website sucks!
