A small community festival that I am on the committee for has the need to build a 20 foot by 20 foot stage, we do not have the budget to rent the proper staging, all of the lumber will be donated by a couple of local hardware stores, this is for a yearly 2 day festival so it needs to be taken apart easily for storage and will be on unlevel ground so it will need some adjustability as far as leg height, does anyone have a source for hardware or any ideas that could help us avoid some of the leaning while you build issues,
