I am not the first to say that getting into this is not a great idea but run with it if you feel decent.
Starting with dish is good because of some of the things you learn are totally valuable if you work up
from there. I didn't do dish long but that was mainly my contractor. If possible buy your materials outside of the company
so you can control some of the screw ups on your check. Contractors always take more than they should and it is always by accident
just like you accidently not getting it back also.
