I simple booth should not too bad for you to construct. I have made a couple from rigid poster board for the side and bottom glued together with a hot glue gun. I use the more flexible poster board running front to back curving up the back wall to eliminate the seem. I tend to stick with white, blue and grey. Some colors will greatly change the lighting and even the appearance of the colors of the piece. Lighting was cheap...couple construction drop lights with florescent Day White Bulbs and I was done. Simple, but yet effective!
Good luck on the building!!
