Simple PHP project- stock trading related

I have a requirement for someone to automate an existing web page using MySql and PHP. The page now is static and the data is entered manualy. This page can be sent those interested. Simple calculations needs to take place using the Stock data provided for free by Yahoo. This data needs to be stored temporarly in a DB, then written permanently on to the web page, as some positions/stock portfolios are closed. I estimate no more than a full day of work is requiered for someone who knows very well PHP and understands a bit about the details of stock trading(opening/closing price, gain/loss,stock symbols..etc). Please bid accordingly!
