Banner Design - 728x50

I'm in need of a semi-animated Gif banner (2-3 frames at max) of size 728x50. The banner is actually about a laptop lucky draw that will allow users to click on that banner and on next page users will be aksed to enter their information in order to participate in draw. So Banner must be catchy to attract more clicks. You must have some idea in this regard. Actual text will be provided though. Bidders with banner design portfolio will be preferred.
