4x4 are $12 for 14 footers , I got some yesterday at Menard's. I use Shadow hunters elavators for my blinds very easy to put up. No digging or cement. I doubt if $200 will get a blind but if you look around there are pieces of wood that you could use.
Here is link with instuctions.

Just get the elavators not the whole blind
