Lots of blind pictures to look at here to get ideas from.

I have built them from free pallets from places like TSC and motorcycle, snowmobile and water craft shops. Sears also has them some times.
You can make a wood 4'x4' blind and mount a bracket with wheels a couple of guys can move to different places and if you add a tow bar you can tow it with a ATV even.
Use the thin fake T 1-11 siding for light weight.
All but the plat form is recycled stuff on this one.
You can buy pre built box blinds all over this area for 250.00 painted and every thing includeing windows.
