Thank you all for the kind words. I have all of you to thank....I gained my skills in the USAF on your tax dollars many years ago.
gunpackinpanda - the cost to ship something of this size is crazy these days. I'm sure it will rocket the price out of range.
You would be much better off finding a local fabricator to make it. If you don't have a marine fabricator in your area I suggest finding yourself a race car fabricator. They are accustomed to working with aluminum and because of the visual nature of their products they usually have very fine craftsmanship skills.
Canadian Dave - use any material you are comfortable with, especially if you are going to weld it yourself. Steel is even fine if you if plan on a properly prepped paint job, or even better yet powder coating it.
