Automated Web Hosting Site(VERY URGENT)

Hi I am looking to develop an web hosting site urgently. I need this to be integrated with my reseller account and be fully automated i.e. it should include billing, domain registration, automatic account setup, e-mail to clients, etc. This website should be very professional and also allow me to make changes to the site. It uses WHM and Cpanel. Recommendations of good domain name resellers will be considered. I will also require one business logo for the site. Please only respond if you have experience in doing this before and can get me up and running ASAP. Also please provide full functionality documentation of the site if possible! NO CHANCERS!!! Thanks Ashraf
