I think the only answer you could give that is 'how long is a piece of string?'. Depends what process is used, how much paint, labour charges etc etc. The only way you'll find out in my opinion is to go to a few garages locally and find out. I remember a reputable (best in the area) Toyota garage in Lowestoft wanted nearly £500 to do the offside rear quarter and bottom half (bump strip down) on my Dad's 480 (some tool had hand-sprayed it before

). But that was a mainstream garage. My Dad done the prep and a smaller garage re-sprayed it for £180 (ish).
You could do alot of the prep work yourself, filling, sanding etc to save money, but you'd be better to get the instructions from the place that are going to do it, as they'll only have to do it again if you muck up. Plus they might not do it then anyway-if you do the prep but they spray it, and in 4 weeks it goes funny, they may turn around and blame it on your prep!
Just get yourself to a few garages and ask, thats what i'd do. But be prepared for some hefty quotes!
Let us know how you get on
