ive been giving 10% for years..if the guy is dependable there wont be a prob.
ie. at one of the local factories, my guy takes all action for football on friday, for sat and sun. i deal them opening lines they post their money up (these are small players 25 and 50)and he turns in the plays and money fri. nite, we settle on tues.
takes all the workload off of you..
IMO...thats the best way to work large groups of people (factories, bars, ect)
