AF Johnson Millwork in Des Moines has a full Autocad file that I paid to convert to their CNC machine format to precisely cut out a full size cabinet with both a 2 player and 4 player control panel. Precise down to 0.0001 of an inch.
They charged a friend of mine $400 for a melamine cabinet cut out in whatever color he wanted. This was a few years back, but it might be worth a call to them. I would NOT recommend melamine. It it hard to get it to glue to itself since the inside and outside are slick, and any screws/nails used will damage the finish. But it could get the hard cuts done, then you could laminate it yourself for pretty cheap.
Anyway, I KNOW that the plans are good, and it is probably under my name, just ask for a price without the melamine, and see what options for wood they give you.
There will still be lots to do:
cover/paint it
cut t-slot for t-molding
assemble
put in the guts
mount bezel
mount marquee
put caster wheels on
etc.
Might be an option for when you do want to do it.
I live near Cedar Rapids now, so I am rarely in Des Moines anymore.
