Numbers and Advice

Hello everyone. Ive been a driver for almost 5 years and did some time in the ag and bulk side of things. Recently ive been talking to a friend about entering a business partnership. Ive discussed with him on my experience on this side of trucking and offered the idea of running bulk loads I.E grain feed lime rock etc etc. Its been a minute since ive been on this side of everything but i was being paid 25 percent of what revenue my unit was bringing in (about 1k after tax) Has the market tanked on it or is it still solid enough to run a route like i used to (Grain to STL area and Lime back to Central IL 4x a day 5 days a week) and still bring in a profit? Im just trying to get some insight on this area again so i can run some numbers and come up with a plan. Obviously planning to run frameless dumps. Also any advice other than the standard youre out of your mind (Im aware of that, my S/O always reminds me haha) Im trying to ride out the fuel hike until it drop (If it ever does) Thanks in advance
