Contact Database Management System

We have a lot of contacts that need management through a PHP/mysql website. These consist of email address, name, phone number, and other information. We need a way of managing them and comparing them against new data we get. We will need a mechanism to import, maintain, and export the data. Importing will involve uploading via PHP upload and unzipping on a server and then mapping into a mysql database and loading. Maintaing will be a bit more complicated and will require smart programmers. Exporting the data will involve downloading the file via the browser or writing the file to the server. it will require a mysql database and very strong PHP skills. I am currently doing everything via text files and several software tools, so getting a web interface as soon as possible is very important. I want someone who can deliver the product and make it fast and effective with very few bugs. I will pay through GAF and will put money in escrow on project start. I would like this project done within 1 week. If not, I will go to the next available Freelancer. Please have a webserver so I can test this project.
