I have always wanted to own a bar setting where guys oil or mud wrestle in front of a crowd full of mostly female because we are entertainers and we wear gear like singlets brief cut bottom, speedos skipper the better, jockstraps, mankinis, thongs or gstrings. That would be the starting pay scale the less you wear the more you would start off making. As for the league it would just be if you are interested would you be willing to come up with a character name, pick a entrance song, what gear you would strip off (robe, costume or at least a shirt) dancing/walking to the ring to get more tips from the crowd the ring would be in the middle.
Would you like to play?
Bottom line if you like what you see go after it.
