Display Banners for top betting site

I'm looking for some blue sky conceptual thinking around producing a set of display banners (football focused) for one of the top Sport Betting companies in the UK. I will be looking for 3 concepts, only as mock ups (hand drawn if necessary) just to convey the idea. If the client likes them I would ask you possibly to design and provide final PSD's. Once you have signed an NDA, I can disclose the name and provide historic examples of what they have done as well as provide a detailed brief. This does require a heavy weight creative thinking. If you are up for the challenge please show me examples of creative thinking / design you have done in the past. Time is precious on this project and I want to get the ball moving as soon as possible.
This job would ideally be for someone who loves football and understands betting and what makes a punter tick! Please get your proposals in quickly, would like to start today!
