Like Civicrice said Practice. Do all of your family and friends cars that will let you. Your work will say it all. Its really up to you on what to charge them. When i started out that is how i started. Did a lot of cars for free and did some just for the cost of the materials. The pricing really depends on where you are located. My main piece of advice i could give you is learn from the mistakes you make and move forward with it.Practice shrinking more than anything
