Idea replies — Building an on-demand figure skating advice app (looking for a tech co-founder)

Before building the app, could you test the concept through a simple video feedback service? Skaters upload a short clip of a jump or spin and pay for a coach to review it with annotations. You'd learn which questions come up most often, how quickly people expect answers, and whether parents or skaters are willing to pay. That information would be incredibly useful when discussing the product with a potential co-founder.
