RE: Does anyone have any ideas for building ladder stand?
Not knowing what your fab skills are or what specific materials you are referring to but this would be my material list:
Perforated Steel (floor)
1x1 in. square tubing (legs, braces & steps)
Ratchet straps
those are basics
The most expensive part to the ladder stand is the perforated steel. Expect to pay anywhere from 50 to 60 dollars for a 4x8 sheet. But the tubing is fairly inexpensive.
