Replying to Freeski lessons

I'm toying witth the idea of trying to set up a gig for myself this winter teaching kids to ride in the park. I have years of traditional instructing under my belt and was wondering if anyone had done something similar. Not through a mountain, but just gathering some groms and teachin em to shred. Not sure if its legal to charge for lessons at a private ski hill without permission, but if its lowkey i don't think it would be a problem.

bad idea? good idea? seems like it would be a fun way to make some money skiing. If I could bring some gapers into the park and turn them into lifetime shredders that would be a blessing
