mariage is the biggest investment you can make in life it can turn good or bad but its allways a big decision , all the best wishes and lots of luck from my end .
if you build the booth inside a barn or something you could construct it from 2 by 4's and plasterboard with isolation in between its nuttin more than a big box with suction on on end and big barndoors with filtermaterial on the other , works pretty good just spray the walls white and with the sticky stuff after that so the dust stays on the walls , make sure you have some beams on ass height and shoulderheight or you fall straight through the wall should you slip
maybe some windows for daylight and a bunch or fluoresent lights and youre done
