You won't find anyone willing to sell never mind give away a profitable bot they've probably worked hard for several months building and encountered many losses and dead ends developing to anyone else and handing over half there future profits from it for the future.
Its a bit like going to a newly qualified plumber or electrician who's just been on a 2-3 year course at there expense and you now asking them to transfer you half there wages each week for every job they do in future
Its going to be down to each individual to come up with there own edge/strategy and then create a bot that can deploy that strategy for them, there's plenty of examples in the Tennis section of the shared files area that will give you some ideas and a starting point to build from but you'll need to be the one who develops them and finds the right type of matches to deploy them on etc
