How To Be An Independent Driver. Where Should I Start? Need Advice.

These are questions from a guy with only google knowledge. May feel like stupid......but thank you for advices.

Hi people, I'm a 26 years old guy. I'm a nurse presently, and I'm thinking deep about a career change in next 2 years or so. I am completely new to this, I'm studying on my CDL learners manual for class A leraners test. I don't wanna spend life as a company truck driver, but willing to do so for a year or so for gathering experience, and learning the equipments. I have two plans in my head.

Plan A. (lease or own) Once getting a year or two driving experience, I plan about leasing a truck and drive on my own. The questions are, HOW TO GET LOADS AT MY OWN CHOICE. BROKER, DISPATCHER, AND LOADBOARDS....HOW DO THEY WORK. HOW FLEXIBLE IS A LOADBOARD WHEN IT COMES TO SELECTING MY LOADS. WHERE SHOULD I EXPECT LEASE, DIESEL, AND MAINTAINANCE EXPENCES. Basically I just don't wanna be stressed out by dispatchers, or I don't want to pay big money to brokers. In other words, my idea is to pick a load from a loadboard starting from Florida (I live in Miami), deliver it in its destination (texas) at the given time to me, pick another one from around area, deliver it in California. Pick a load from California, deliver in Alabama. Pick some from there to Miami..making a round in the country and getting back home after 3 weeks, take a week off, get next load whenever I need.....repeat.............At my present job, I make about 3500 monthly after all taxes. Is it possible to make something similar or better with my plan A. Eventually I wanna buy a truck on my own. How realistic is plan A.

Plan B. (HAZMAT, Iceroad...only if plan A fails) As a company driver itself. 1. My paln is to do HAZMATtanker jobs in oil feilds. HOW MUCH DO THEY DRIVE, HOW MUCH THEY MAKE WEEKLY, HOW IS THEIR LIFE STYLE. 2.HAZMAT tanker jobs regional driver, HOW MUCH DO THEY DRIVE, HOW MUCH THEY MAKE WEEKLY, HOW IS THEIR LIFE STYLE. 3. Seasonal ice road trucker, HOW MUCH DO THEY DRIVE, HOW MUCH THEY MAKE WEEKLY OR ANNUALLY, HOW IS THEIR LIFE STYLE. most important IS THIS JOB HIGHLY IN DEMAND ? (ready to move to Alaska or wherever).

Thank you for you time.
