WebSite Design

I need a webpage that will allow unlimited number of individuals to login and setup up a profile on their own webpage for example: [login to view URL] the next person page would be [login to view URL] and so on. And allow visitor who visit the individual site to upload .PDF, Microsoft word, Word perfect, Microsoft works, .doc Files only and the file maximum size is 350kb for those files to be viewable after they have been uploaded. The visitor of that persons individual site can only view documents and upload documents after the visitor has enter the personal pin that the Individuals(owner) of that webpage has assign to their page to be viewable by visitors with out the code the visitor can not access the Individual(owners) site. The owner of the profile how ever can edit there personal info that they and the site administrator (Me) can see. The owner can delete what ever uploads they want, but can not alter or download the document but they can print it out in a professional print format. All upload has to be stamp by the site administrator (me) after verification. The verification work like this: after the Visitor upload a document an e-mail is sent to the visitor. The visitor will then have to reply by typing the last 4 digits of there social security number. When the person reply a approve stamp will be embed or place on to the document top right hand comer. If verification is not received within 2 day a notice is sent to all 3 parties the individual who uploads the file, the owner of the page and the site administrator. The upload page will have a form and a browse button for the visitor to find the doc on their pc that they would like to upload, their also a download button so they can download a template. Then there’s an upload button and a submit button. The form will ask for First and last name, School you attend, position in school, School Address and Phone Number last for digit of there Social.
