you can get custom transformers made in lamington tell the guy about the transformer winding ratio. Also as u have to drive laser diode i dont think u will require smallest possible transformer. may be 500ma sized.

there are two shops in lamington who make transformers. once you go from lgrant road station to lamington and as soon as you undergo the bridge you can see that shop on your left hand side. also there is 1 more shop just before that bridge starts. but that guy is very expensive

Did you try hacking one out of some old dial up modem ? Might just work out.
You could also look at some audio/telephone shops and see if you get something close.
8ohm and 1000ohms are not "holy" figures :)
Did your CNC thing work out ?
