This is what happens when you try to manage something that you have no idea how it works. Again, hence the $5 million.
First, you need to go to school & get your own CDL, become a company driver for 5 years minimum, learn the industry & save your money.
Then buy a truck by putting a down payment on a truck, get the required insurance all required paperwork & have 6 months worth of revenue on hand for rainy days.
If you have the money required to lease a truck, you need to invest that money into buying a truck.
Actually hauling freight requires risk, uncertainty and expense. On the other hand, brokering freight just requires a telephone and an app. You can start a brokerage or a trucking company that only hires O/O, L/O and then forces them to use your dispatch only. Either way you get your cut before a single mile is turned. Flat tire/speeding ticket/I-80 shut down for weather? NOT YOUR PROBLEM!
