Banner design for Website

I am looking for someone to create a few banners and 1 image for my business website. I require in total 6 banners and 1 image to be done. These both are simple jobs and easily can be done by an experienced designer. I will also provide examples as well which would be helpful for you to understand what I need. I would like to have nice looking banners made that fits the theme of the website. Please note I would require high quality banners/headers as they will be to promote my business. Maximum budged for 6 banners and 1 image is £20. Work should be finished within 24 hours. PM me with your proposals. I would need to see some previous work done of yours in order to select the winning bidder. Thanks
