Stageright Multipurpose 3 x 8 deck panels

I am looking for a very large quantity but will buy any quanity you have. I need a total of 550- Stageright, all purpose deck panels, size 3 x 8. Each panel will have guide holes in each corner. The floor surface can be anything. Will pay reasonable price but would like to get the best deal possible.

My price range is $20 to $80, depending on the quantity available and quality. Transportation is no problem since I can arrange freight shipping to pick up most anywhere. Thank you.
