Alright this was my first shot at using Google sketch up... took a while but this kinda gives you an idea what im after.
these colors relate to the picture
Blue = 2x4's
Green = 4x4's just cause i already have the wood
Red in left corner = Not using a 4x4 here because of the corner overflow so 2 x4's are used here a little away from the corner
Purple = more support which are 2 x 4's
Total stand i think is going to be 30"' tall
