facebook script

We have a couple of thousand facebook account which we use to provide likes. We need someone to create a script that can access a database with the accounts and passwords, autmatically login to facebook, like the provided page, and logout again. If you already have the script kindly provide me the price. To launch the script there should be a form that allows me to enter the following information: 1. link to the page to be liked 2. number of likes (i. e. 1000) 3. range of user accounts on the database (i. e. 1 - 1000 or 1001-2000, etc...)
