Are you sure you guys know how to use iMacros? The idea here is often not to just come upon and/or find working macros, but to put forth some effort to overcome the obstacles to your success.
You need to MAKE your macro guys. Go to youtube, and just search for a good iMacros tutorial, or even just use Big G to find something. This stuff is super easy, but learning to do it yourself will be so much more valuable than asking in a forum like this for a cherry-picked solution.
Hit RECORD, and perform the functions you need to browser to do, then STOP recording. You might need to tweak some things after, or learn to use .csv files or other things, but it's too easy not to do.
Good luck!
