I worry about the liability aspect of the whole thing. Better have great insurance when you have Soilfloc-ed your pond and the fisherman comes in, paid good money, and goes for an unexpected swim and cannot swim.
But if there is something like the local snowmobile clubs have with a group insurance for all members. The pond owner (land owner) signs up to let the personal pond be fished with restrictions and contract, they can share in some of the fees as incentive to open the pond. The insurance is paid for by the club and the land owner is covered.
