Trying to tweet @ the people I follow

Hi, I’m trying to simply tweet the same thing repeatedly @ the people I follow… I’d like to put 4 or 5 @ in front of each tweet and tweet it until I run out of accounts… I don’t know how to work out such a campaign… can someone help?
Basically I’d like to do something like this:
[FOLLOWING1] [FOLLOWING2] [FOLLOWING3] [FOLLOWING4] Yo guys you have to click on this link! Check this out you wont believe it!
where [FOLLOWING#] is the people on the list of people I follow… until I run out… and then the campaign stops.
Can someone help me do that?
