Well doors aren't that expensive, we got oak veneer ones for less the £100 a go. Do you have to have intumescent strips or smoke strips? I think for the frame it is just the case of having deeper\wider door jambs.
No idea of labour cost, but shouldn't be much more than hanging a normal door, putting in the strips does mean they need to router all along the edges, but not more than half an hours work to do that.
