Raising the curtain...s

Hi, Got a question... I've got a stage, it is circular but not rotating and is 6m in diameter. The stage is divided into 4 sections by scrim curtains, so imagine a pie with four slices cut out of it. I need a method of raising or drawing these curtains either horizontally or vertically at a slow pace, as they are acting as a 'mental barrier' which is lifted. The budget is $10,000, so not much in the grand scheme of things. I know I could use a pulley system, and rig it myself or get Showtech to do it, but the pulleys would need someone to pull them obvious, and we only have 2 SM's, myself and one other, but I'm going to be operating lights. Hiring extra crew isn't really an option as the directors are paying for us all to get to Adelaide. I'm also trying to decide whether to use 4 seperate small curtains, or to use 1 long curtain to cover the diametre and then 2 smaller curtains to cover the radius?? What do you all reckon? How shall I tackle this beast?
