Design Twitter Page, Facebook Pictures/Design, minor Wordpress work

Our company is working on a "drink" themed iPhone application and we need some help designing a few social media components. We need a Facebook Landing Page, Twitter Background, and some graphic design work. Here are the specifics on what deliverables we are looking for: Facebook Page- Custom Cover Photo Design including some of our current image assets, Adding custom shots of our app in an iPhone screen, Photoshop pictures of people using our app as well as a similar (cover photo image to use on our Facebook App page. Twitter- Custom Background with drink theme using our image assets. Some photo's and images from FB landing page can be used to save some time as well. We are looking for a quick turn around and if possible we'd like to have the project done by the end of the weekend so we are looking for someone who can work fast and has a time zone not completely the opposite from ours. We prefer to work with someone during decent hours from 6:00 AM PST until 12:00AM PST. Thanks!
