Looking for mass account twitter script

I'm looking for a script auto-tweet, where I'm able to add a list of users and passwords in big text field. In the next field, I can add the text I want to tweet. On submit, the script will post/tweet that message using all of the listed accounts.

If someone are able to code this, I'll willing to pay a small sum. I need script to be done within 1 day and will only be paid when i see the demo.
If interested. PM me with your MSN,
