Moveable iso booth 8X10

Hello! First I want to say thanks for this site. It was of great help more than once. I'm planning on building an iso booth on wheels for my studio. The setups in my recording room are changing all the time so I need to be able to move it around and even disassemble(???) it once in a while... Is there any plans available for that kinda booth. I can certainly built it myself, but I would like to get some advices and ideas for this. I'm trying to keep expenses as low as possible. Doesn't have to be 100% sound proof. Mostly I wanna get rid of low to low mid frequencies (my building rumble noise is between 30hz-300hz). Any link or past post are welcome. Unfortunately I couldn't find any with the search engine on the site...
