Design 4 Website Mockups with Graphs - GUI Design

We are planning to create a web-based application, which displays a lot of graphs, pie charts etc. For the first step I need some mock-up designs of the GUI. We will provide you with hand drawn illustrations which will show the basic content (but of course not the final design or color scheme) - similar to the pdf you will find attached. You will work on four of these. We need you to complete the job within 2-3 days. I would prefer a designer who can show me some reference work on graphs and chart design. As we might have some last minute changes, please also provide me with your hourly rate. I need a designer who is fluent in english as i would like to further discuss the designs. This will be a first start project. If you do good we will let you do the full gui design of the tool in a couple of weeks.
