php/mysql - multimedia workflow manager(repost)

we need a coder plus designer? who can design and develop a multimedia organisation plattform for us. the shortversion: we need a online software portal where our clients can manage their workflow for a digital product. so it is something like a multi-project management software for digital goods. you start a project, create ideas, stuff people, create dates, upload results, let those results be improved by team mates and finally contribute them. the portal has three parts: a) the standard-startpage where we describe the portal and let the client subscribe for our solution. here we need a fresh and clean design. e.g. something like this [[login to view URL]][1]? with little videos and information about the tool. b) than we have the area where the client can handle his work? - here we need clear working project management environment like you can find it here [[login to view URL]][2]? and <[login to view URL]>? // all features inside this two tools need to be in our tool as well c) the backoffice interface where solutions and tasks are shown to the backoffice stuff you also need to implement automated payment systems throu credit card and paypal. your first step inside of this project will be to develop the final concept due to prototype design (jpegs/layouts) and than the final working PHP/MySQL based solution.
