Revamp of Client Portal

ok, so here is the deal. We currently have a client portal that needs a complete overhaul. The current portal started simple and then just had feature after feature added till it now looks horrible and very old school web. I am looking for a very fresh and easy to move around portal while keeping most of the current features. There will be a need to make the system easier to use and more user friendly. You will be writing this in \members so that we can keep \clients going. The database is about 1.5 gigs and is mysql. You will need a very good understanding of mysql because there will be some optimization needed during this project. The only thing I want used from the current system is the database. Same user/pass info but this members will only be for clients not the admin side. For that we will still use \clients This is an executive style client portal which means the reporting will need to stay intact but optimized to look nicer as well as function better (mysql/php optimization) There will be a need to create a few more reports as well. Right now all of the reporting is on 1 page with buttons to various other reports (ugly) I am looking for each section to be on a new tab within the members area and then on each tab, we have general stats with nice ways to view the reports. Each report will need to be exported for both excel (csv) and pdf. I would like each column to be sortable as well. We will also need date ranges for the member to select. Most of what I mentioned is already there but its very hard to use. Please think easy to navigate, as again, its for an executive level manager that honestly just wants things to look nice and to find what they need easily. You WILL have to sign an NDA if you accept this project. This will be a longer term once the initial is done due to new features we want, you will be our goto for the member area. If you bid, I want to see samples and I want to hear how you have handled something like this. If you just bid and no comment, honestly, I will not even look at your bid. Time frame is 2 weeks. I am ready to start now.
