Looking for some spruce lumber

I am looking for some spruce lumber. I only need about 5 or 6 bd ft, preferrably in 5 or 6 foot lengths. I am going to build a crackerbox, which is a RC boat, usually powered by a weed wacker or chain-saw engine. They are about 4 to 5 feet long and go around 30 MPH with a stock engine and can reach 60 MPH with a modified engine.

I got the plans, engine and radio equipment, just need the wood and HW.

I can get the 3mm Okuome plywood I need for the shell, but finding spruce lumber is a different matter. Though I think some of the 2×4 material at HD is spruce which I could cut down to the sizes I need…
