How much to cut and thread a 1" fork?

[xroads]

I have a 1" fork with a 10" stem of which 2" is already threaded. However, for it to fit my hack bike, it needs another further 1" threaded, and 1" cut off the top. How much should this cost to get done at a bike shop?

you'll be looking at around £10 to £15 as it has to be rethreaded.
