I used to do this a lot for Pacific Bell - all by myself. I created my own scripts; they aren't difficult at all. Here's my method:
Group all your like models of routers together and stack them them on top of each other, plugged in and booted up. Get a copy of a terminal emulator (HyperTerm or whatever), the IOS image you need, and a TFTP server on a workstation. You'll need a console cable and an Ethernet crossover cable too.
Console to the router and configure the router with a temporary e0 (or e0/0 or whatever) address on the same subnet as the workstation. Now go through the motions of TFTPing the image to the router. When you're done, just copy all of the information you entered into the router to a text file, e.g.:
config term
int e0
ip addr 10.1.1.1 255.255.255.0 (assuming the workstation is on the 10.1.1.0 subnet...)
no shut
exit
copy tftp flash
10.1.1.2 (workstation IP)
c1600-y-mz.112-16.P (image name)
y (answer to 'do you want to overwrite current image')
y (answer to 'do you want to erase flash')
(I believe you will have to enter the final carriage-return (Confirm?) manually.
Sit back and watch the !!!! go by. When they're done, reboot the router, switch your cables to the next router, and dump your text file to the terminal emulator to start all over again. When the last router is done, you can switch your console cable back to the first router to confirm that the new image is working properly - and as long as you never saved the config, the ethernet interface will still have it's original address.
Hope this helps. (BTW, it's obviously even faster if you can use a FastEthernet interface...)

Subject: Scripts for IOS upgrades
All,
We support over 500 components and different models of Cisco hardware. We need
to upgrade IOS levels in a fast way.
I would imagine using some type of script with checks and balances would do the
trick.
Has any one used such a creature...?
Where could I find a creature like this as fast, as fast can be...?
Thanks in advance for your help.
