I did the floor pans on my 280zx myself, well with help but you get the idea. I live in Calgary too so if that helps great, but for places to reccomend for metal I think the place is called Calgary metal & salvage and they got alot of metal for good prices. I used a 20 guage metal on my floorpans, i think thats what they used stock. It would save you alot of money to do it yourself, plus you can make any changes that you may want.
