Batch Rename Advice Needed

Question

Specifically, how can I move 6 characters from end of folder name to beginning?
From this: "test name 082508"
To this: "082508 test name" or ideally this: "0825_08_testname"
Looked into every app I could find as well as automator,but can't seem to figure it out. Need to change about 2000 folder names, so batch is key.
Have access to a PC as well, but Mac solution would be preferable.
Any help appreciated! Thanks.

ok, assuming all of this folders sit in one big folder which has nothing else in it.
run the following apple script. it will prompt you to choose a folder. choose the folder containing all your folders that have to be renamed.
<pre style="
font-family: Monaco, 'Courier New', Courier, monospace;
font-size: 10px;
margin: 0px;
padding: 5px;
border: 1px solid #000000;
width: 720px;
color: #000000;
background-color: #ADD8E6;
overflow: auto;"
title="this text can be pasted into the Script Editor">
tell application "Finder"
set mlist to entire contents of (choose folder)
repeat with cur_item in mlist
set name1 to text 1 thru -8 of (name of cur_item as text)
set name2 to (text -1 thru -6 of (name of cur_item as text))
set name of cur_item to name2 & "_" & (do shell script " echo " & name1 & "| sed 's/ /_/'")
end repeat
end tell</pre>
