[Caseys Painting]

Hey everyone. I am 24 yrs old and have recently started my own painting business. I specialize in interior/exterior painting, interior/exterior staining, and powerwashing. I would also like to get into deck construction and repair...but that is down the road.

Question...What are the most important things I should have "in my back pocket" as a new contractor? Insurance, certifications, taxes, etc...?

What did some of you guys overlook and would now do differently when you started out???

Thanks for the help!
