Designs required for web and app graphics

I am looking for a designer to create some graphical icons to use on a business website and within a mobile app. I don't want comic book style artwork, I would like graphical icons and illustrations.

The images on the App Figures homepage are an example of the kind of style that I am looking for http://www.appfigures.com/

I require approximately 6-8 icons to be designed as soon as possible. I am working towards a deadline of Tuesday 14th February.
