Designer to create & develop flow diagrams & banner graphics

Hi everyone! I own an affiliate marketing website that will soon be relaunching to the public. I need a few graphics made to be put on various pages of the website. These graphics will be relatively medium-sized "banner" images. We are specifically looking for the following few graphics to be made: --flow/diagram of how the affiliate marketing industry works --banners advertising/promoting the relaunch of our site --various other "catchy" images that we need on different pages of the site These images we need constructed will need to be original, and we are not looking for the inclusion of any "stock" business images. Also, we will need recurring graphic design support over the lifetime of the site and would be more than happy to enlist in the services of you again if your work is up to par during this first round of requests! Thanks, and I look forward to hearing back from you all!
