ColdFusion / SQL > PHP / mySQL HELP!

Hi everyone, Ok, I need serious help. I have been handed a project by my boss to convert an existing site that was built using ColdFusion / SQL into a site that will use PHP / mySQL. The site relies heavily on calls to the database for everything from site content, to an admin area where you can edit that content, to a news ticker, to the actual navigation of the site. What's the problem? I have one week to do this. Oh, and did I mention that I know VERY little about PHP / mySQL. I know NOTHING about ColdFusion or MSSQL. And to top it off, the site in question contains over 300 .cfm files! Does anyone have any idea how I could pull this off? Even if I had a working knowledge of ColdFusion, MSSQL, PHP, mySQL...still one week isn't enough time to retool a site of this proportion. Especially considering that I don't understand any of the code that I'm staring at. I've been a web designer for about five years now. Notice I said "designer" not "developer". I want to learn PHP / mySQL but in order to complete this project I also need to understand ColdFusion in order to replicate the site functionality. Any advice on what I should do? Thanks in advance for your help, Chris
