Well. if you don't offer enough money for the load, nobody will haul it and your customers will lose your phone number, If you pay to much, then you won't make any money, I have dealt with a lot of brokers over the years some good, most though are about on the same level as injury lawyers and used car salesman. Brokers are a necessary evil and I think maybe more so in the future as these big companies start cutting more of their sales staff and rely on outside agents
Some brokers take up to a 20% cut, depending on different variables, the honest ones will keep his rates low and steady around 7 to 10%, some have been known to hold bidding contest for the load, just how low will you run it for type thing, I have known brokers to have two or three drivers on the phone for the same load and that is where the dishonest broker starts robbing the drivers. Word gets out though, for example a broker we used here (Pembroke transportation) was caught doing that. Us driver were all from around here that hauled for him, we always picked up out of the same two aluminum factories going to mostly the same customers, it doesn't take long to get to know everybody and when the numbers start getting compared and found to be different for the same loads, some drivers can get upset,
