Display Solution..
There's a lot of plastics companies in my Yellow Pages.. A few years back, I had to make a clear wall & counter for a corner store. We ended up buying a few sheets of 3/4 thick 4 X 8 sheets of clear lexan. It was expensive that thick, but, the thinner stuff, 1/4 inch, was pretty reasonable. It wouldn't be that difficult to walk you thru making a built-in clear wall to display a larger collection. Tape measure, stud finder, circular saw, router/trim router, and a drill. If you can get ahold of these, you'd be done in a few hours. If you wanted individual shelves, that's another story, but a shelf 4 feet down from the cieling, up to 8 feet long, only takes a few hours. Once the first one is up, adding more is a piece of cake. Years ago, I made aquariums. A glass or plexiglass wall is pretty easy..
