I need two banners.
sizes: 600x120 pixels, and 423x180 pixels.
It's likely I can get you some graphics from the site so you can make the ad look like the site.
Ideally, I'd like two banners for each size so I can split-test. So the two variations of each banner should be quite different looking to start in order to see a clear direction to go with.
There may be the possibility for more banner creation in the future if split testing is proving fruitful.
I will provide the site URL on request for you to begin formulating your ideas.
It might be nice also if you could show me a quick rough draft before I commission you for the job.
Also, I'd like to see a portfolio or website that showcases your abilities.
