I have a turritopsis jellyfish that I'm thinking of raffling. I was going to do the jellyfish along with a random marking applicator, a marking remover and a lab test frog. How much should I put for the price to buy a ticket, and what would be good items to put down as acceptable tickets? I also wasn't sure if it would be better to do a winner takes all or a standard raffle. Any advice would be greatly appreciated.
