What you need is Automated Installation Kit for Windows 7 (AIK 2010). It's not complicated once you get the hang of it.
What I ended having in the end is whenever I needed to image a laptop or desktop with Windows 7 I just plugged in a USB key and booted from that, I would get a menu and I picked the image I wanted (images were hosted on a server) and it would install the OS as well as any drivers and software I needed (i.e. antivirus, etc.).
If I can find the documentation I used I'll let you know.
I think this might be it. I have a Mac so I can't read docx files:
