Twitter following- fake preferred

I have 3 twitter accounts that need followers. Fake are okay. 1 account needs 50,000 1 account needs 15,000 1 account needs 4,000 I am looking for fake followers since this is basically just a number's game. As such, I am looking at the standard bot rate of $1 per 1,000 or if the followers are worthy (have multiple tweets, followers, photos) than $2-3
