Build me a data driven service portal.

I am planning to build a database driven service portal with paid access to content. Key featurs of the portal will be: Admin Level 1. Upload Data 2. Manage Content Security Rights 3. Manage Access Control 4. Manage User Registration & Payment Processing 5. Manage CMS - Create Templates, Manage Templates 6. Tagging of Content for to put in an appropriate structure - taxonomy User Level 1. Access to Search Interface to Query Data 2. Present Data in Tables, Charts (Live Charts, preferably Integrated with a third party tool - Hicharts) 3. Access to Articles (posted through CMS) 4. Cross-linking of Tables, Charts with articles 5. The possibility of integration with open source BI tools I want to use Open source technology, the idea is to keep costs to minimal. A relational database is available in Excel, which will need to be migrated to a more professional open source database like MySQL. I am inclined to use PHP as my front-end. Happy to use plug-ins or any readymade tool which makes the development process swifter. Other Information: There are about 6-8 Transaction Tables About 10-15 Master Tables Project Duration
