4x4 would not work? what about 4x6?
Penny wise. Pound foolish. A standard way to make posts these days is too
nail together three 2x6. Use pressure treat below grade. Stagger the joints
and use gorilla glue. Also, a concrete cookie should be under the post in
the hole with a special bent rebar the hooks into the post. Very cheap and
keeps building in place during a thunderstorm.


What about a package from your local builder?

Excellent idea. They will provide the most cost effective design, give you
guidance, and deliver.
