PHP on Linux to Microsoft MS SQL Connection

I have a Linux VPS web server that is running PHP 5.2.17 and Apache 2.2.23 that needs to connect to a Microsoft SQL server 2008 R2 that is hosted locally. I am fine installing FreeTDS or any other application to make the connection on the VPS, but the application cannot affect the current website or any other account on the VPS (there are a few hundred). I will have to do all the installing, you can just let me know what you need and I will run the installations. The connection will ask the user for their ID number and password. Once that is entered, it will print out all of their fields in the database. The website URL does have an SSL certificate that can be used for a secure connection. Once the connection is made, it will then need to be integrated into a Drupal website. The integration doesn't need to be a full integration (no calling is done with Drupal and no user integration or anything like that), it just needs to be displayed inside of the content area, so whether that is with an iframe or whatever, it doesn't matter. Please let me know how long this will take, when you can start, and write "I know I can do this for you" at the top when you apply, just to avoid the influx of people applying without reading and it will help weed these out. As always and unfortunately, I need this as quick as possible. Thank you
