Yes there are outfits that pay 90% but most that I know of are just small fleets started by o/o and they make you pay for everything
1,000,000 public liability 100,000 cargo.plus your bobtail
and if your gonna go that far you should just get your own authority
cause the only differance in the start up cost would be $300.00 the cost of the authority.
Ive went this route before it cost about 7-10k per year for the insurance. but you can pay a 25% down payment and the rest in monthly payments that run around $500 per month.
so I guess it really depends on how hard you run but if you average 2,500 per week for example your check would be about $500 more per week than running for one of the well known expediters so in a year you might gross 20k more but would pay out half that in extra cost.
plus most of the outfits that pay that much dont give you advances.
and thats why im dispatchn1 its easier to just get your own authority and just dispatch myself and collect 100%.
of course I dont like to mess with collections so I pay a factoring company 7% and get paid next day on everything I do. good luck at whatever you decide.
