You must have signed a contract with that trader a year (or more) ago. So I guess they need to be paid as per that contract. In case you're looking to include profitshare in a new contract, prop firms pay about 50%.

It's where the big trading starts happen. The less you know the person the less is responsibility problem in case of bad results. Agency risk problem...
