UI designer/ developer (HTML5, CSS3, JQuery, PHP, CMS)

It is basically to build a web application with custom content management system. The application would require a secure client area to quickly manage files between admin and your clients through this application.

AS USER:
Order graphic work at a click using a Jquery calculator form with mode of payment being paypal/ credit card/ bank order.

Clients will login and see all and any projects available to them.
Once a user opens their project they will see a basic file manager that gives them the option to open (if possible) or download the file.
They are also able to edit their own settings as well as contact admin through the secure client area.


AS ADMIN:
You can create new users within seconds and add files to the users project page in an instant! to download.
You (as an admin) will have access to:
Create/edit admins and users
Create/edit projects
Allow/disallow clients to upload files on a per project basis
Allow/disallow clients to download image files
Upload any file type
Upload/edit/reorder/view/delete projects

Sample site I'm looking at rightbanners.com. I would pretty much love to achieve the same web application.
