Development of Online Display Advertising Creatives

I need the following online advertising creatives developed for www.SiteApps.com. I am launching this product and running a sweepstakes giving away a $1000 Apple Gift Card & 1 Year of Gold level service. I need the following sizes created (No Rich Media) - 728x90 - 160x600 - 300x250 I am open to suggestions on the layout and content of the creative. I would like Two of each Ad Size to be developed. I want them to be clean, clear and concise. They should highlight the [login to view URL] brand and the Sweepstakes prominently. FYI, You can not to use the Apple Logo, but using the word “Apple” will be ok. The sweepstakes promotion will run for 1 month. Users will get 1 entry just for signing up for the [login to view URL] product. If they implement the [login to view URL] tag and generate Server Calls than they will receive more entries. It is a completely free sweepstakes and users only need to sign up to be entered. Please familiarize yourself with the [login to view URL] product and the apps in its marketplace. Let me know the time requirements needed to complete these assignments, the overall cost and questions or comments that you may have about the project. Please also submit links to sample display advertising creatives that you have developed. Thanks, Mark
