Data extraction from site

Hi all freelancers, I have a page that is similar to the one i'm requesting data from. What do I need? I need an application written in php that accesses the website, extract the daily message (atm: Smartschool message and then an image) that is in the table. That message should be stored in a variable (including the HTML around it, which means the table and layout). My budget for this is very low, so high bids won't be accepted. I also require an working example on my server before I release the escrow (or paypal)...
