If you go the DIY route then go to Blackrock Glass, Rich Glass or someone similiar they can have the glass made to measure, you can get the fittings from places like Haefele or Frank Flanagan Fittings.
If you go the supply and fit route then a good Glazier ought to be able to do it for you but I think something like this would be expensive to have installed.
You could try the Blue Glass Studio, Stephen is a good man knows his stuff.
Or you could try Leadline, Churchtown Glass, Joe also is good at what he does.
Hope this is of help to you.
