Install Windows 7 from external USB hard disk

Question

How can I install Windows 7 from an external USB Hard disk?

I format many computers a day and need both 32-bit and 64-bit versions.

I was wondering if I could launch an hypotetic 'live' installer and then load the wanted .iso from my external memory ?

NB: this is not a duplicate of How to setup Windows from an external hard drive?
