For a two man stand your probably looking at around $ 150 or better. If your serious about building one you can probably do it for around $ 80 to $100 for all the lumber, screws, etc. Then you have to lug it into the woods and put it together. IT WILL NOT BE MOBILE, at least not easily. I would suggest buying one to make your life a lot easier. They all come with safety harness's which if this intended for use with your child I highly recommend using.
$150.00 Your shopping at the wrong place.
