I'm looking for a script that can take the information from (see the example1.jpg below if you don't want to click on link):

http://www.liquidationchannel.com/tvauction.html

from in the "Current Auction Item" just needs the description of the current item, and the item number, not the price, and send it to a Twitter message from my Twitter account.

An example (if this was the current item):

14K YG Tanzanite (Rnd 3A 1.65 Ct), Dia Ring
Item No : 598451

The current item would be changing every few minutes. I need to Twitter the current item every time it changes. Sometimes the current item changes fast, sometimes the current item changes slow.

I need to have a password protected back-end admin area to where I can put the Twitter account information, and add any extra message I can add to the auto-fill message (like website information or something).

Please let me know if you need more information.
To answer some of your questions, and also provide more information. Even though I prefer PHP programing over ASP, the servers of my employer have .aspx extensions. Can PHP run on a windows server? If so, I would choose PHP. But, I'll take anything that will work.

If you need to know, I can confirm with my employer what servers they use. Please let me know.

Also (to make things clear), a web based script is needed, with a back end ADMIN area, so I can change the Twitter account info, and add any new verbiage to the message.
