split shift driver

My friend and i are looking into leasing a truck on to a small trucking company in my area to pull local walmart dedicated. I have a fresh CDL but he has been driving for 20+ years and has owned his own company. We are looking to run the truck 20-24 hrs a day split shifts its all local runs about 500-700 a trip per person per day at 1.29 a mile plus i think its 40 a drop also. They pay plates and cargo ins we supply tractor ins. I know that we will not get rich doing this nor do i really want to i just want to make a decent living like everyone else. I have another question im not sure about fuel surcharge and stuff if any of you would like to explain that it would be great. thanks guys
