The Chalk Bucket forum has a thread on this topic.
Cost in the USA runs $100 → $350 for Floor.
Free → $150 for Beam.
If you want professional choreography, check out Precision in Los Angeles.
At my gym kids have paid as much as $450 for a Floor routine. Buying a “used” routine is normally 50% of the original cost.
Leave a comment if you can add to the discussion. Price for quality varies wildly, it seems to me.
