Need a form page/list

I need an easy task.

Simple page with a form where you paste a tweet with less of 140 characters and choose randomly and automatically from a list of users to mention (without repeating) and it fills until it's 140 characters and generate multiple textarea's next to a tweet button

Php/jquery

Search the BST area for someone who can do this for you. Also, this should be posted in the "Want to Buy" section.
