Flash And Php Cms 2

Hi,
I would need someone who could set up a script that wil allow changing text to a small site.
You can have a look at the site at http://fullmoonparty.com.ar . What needs to be dynamic is the text you see on the left , party date, then on the “next party” section , the text to announce next party.
Not european so not big budget but more small jobs in future.
Thank you
