I will write the PHP file so that it only requests the information once per day -- that is, only the first time the script is run it will pull the information needed from Wikipedia. This way, it will not need a proxy or be banned by Wikipedia servers for scrapping. All of those other bids will not be doing this, and this will cause you problems in the future if you utilize this script frequently.
I will also provide support after the project is finished to ensure you get it implemented correctly on your server(s).
Thanks,
Matt
