Great tree farm out by Devon, good prices. That size, should be not too bad to plant yourself. I bought some columnar blue spruces from them---they grew quick and look great. Don't forget the rusty nails in the hole--makes them nice and blue. I do bit of this stuff, PM me for details.
Try 4D Hills ... They are located SE of Edm but do a lot of city work. Honest, fast, reasonable. We use them a lot at SPFGA. I think their business # is 780-662-3232?
