Cost of deck replacement

I'm located in San Jose, CA. and have several questions on deck renovation 
project.

My deck is pretty old wooden construction and I'm planning to replace it 
completely including the frame. Probably will do composite for the surface

and redwood frame. Deck is about 1000 sq.ft and is elevated about 1ft
above 
the ground, no stairs, just couple of steps to the backyard.
What is the typical cost of deck replacement labor?
Which composite material would you recommend? I'm thinking of Monarch
Exotic 
Tigerwood, which I found from local dealer for $2.85/ln.ft

Would really appreciate good advices and approximate estimates.
Thanks.
