PHP Autopost to multi twitter accounts script

We are a large adult website looking to create a long term partnership with a good reliable php script writer Our initial requirement is for a script (probably PHP) to automatically post links + image to multiple twitter accounts. We have around 300 content producers (only some of which have twitter accounts). Each day we post content from say 8 - 10 producers Once a day, the script would need to check our database to see if that producer has a twitter account (and has authorised us to post) and post a link together with an image to that producers twitter account
