Need 20+ Web Site Graphic Banners in PNG format - plus a few graphics

Hello, I plan to first hire 2 or 3 designers to do '1' banner (so feel free to bid fo 1 banner accodingly) as i need to understand your abilities before i give you the rest. We have several large site roll outs planned this month and next, and if you are prompt/good - we can get you substantially more work. See the attached PDF document,. for a full break down of what we need - but in short this is for a web hosting / datacenter web site and you would be doing the graphics for the top of several pages. We also need just a couple of interior page graphic images as well. To be fair, best to use the 'per hour' method for this to be awarded the project. TIME IS IMPORTANT AND WE WANT ALL DONE WITHIN 1 WEEK for this project.
