573267 Website design and set up

I'd like to have my website redesigned, which is intended for my web hosting and web design service. This site should include a domain name registration module that allows search and register and collect payment,(affiliation with any registrar may be considered), an ordering system for web site design service that accepts paypal. The ordering system can be used for both domain name registration and design service. A shopping cart may be needed so prospective clients may pick and order the services. Also if possible, I'd like the site designed in a way that can be edited through a back-end control panel. The system should be simple and easy to manage. The site should look professional. If you have good ideas about what features should be included for the site, please feel free to recommend. This is a serious project. Budget is tight, but once a bid is accepted, payment is guaranteed. Prefer a web designer who has done similar projects. If possible, submit references. Thanks.
