Webcrawler for Traffic Stats / Php Script

Need a simple php script that will be added to another custom built php script. What I need: A script the will pull pageviews per day, Unique users per day, and a screenshot of the site it is pulling the stats for and will post this info on a page. This is something like alexa only way less complex, All I need is the screenshot, unique users, and pageviews. I do not need anymore then that. Basically when a user on my site adds his URL your script will pull this info in real time. I need this to be coded in php4 using MySQL and it must be easy for me to add the coding to other pages. Also must have the ability to set the days for stats to be updated, If I choose 24 hours then it will update the stats every 24 hours starting from 12:00am. DO NOT try to put together something from Alexa and try to sell it to me, I already know about their WebInfo stuff with Amazon and that is NOT what I want to use. I want to see demos, if you do no thave a demo then please do not waste my time. This is not that complex of a script to make and should not take a good programmer anymore then a few days to do. Bad feedback users will be ignored.. Payment will be made after I have the script and I know it works, not before then!! Any questions, ask.. James
