IDIQ Pricing Template

The company I work for is proposing an IDIQ contract. I'm not the pricer but it seems that the way we're pricing this thing is not appropriate for IDIQ. The previous company I worked for was able to create an IDIQ pricing table which while somewhat convoluted, allowed the buyer to compute the unit price at the time each order was placed in accordance with a base price escallated by order year and applied discount based on quantity ordered .... does anyone have a template like this or know where I can find one? I'd like to share it with our pricing team.
