Footlights

I have the task of creating footlights for a production of "She Stoops to Conquer". I did this in the UK once and was able to acquire at very reasonable cost vacuum formed plastic sea shell style reflectors to fit onto the battens I built. I have "let my fingers do the walking" in various yellow pages and google searched for what I want and have found them overseas but not in this country. Is there anyone out there that can advise or help me? I live in SA but would be willing to pay reasonable postage from interstate. Purchase is preferable to hire as I expect to have on going use for these items.
