Diy Stucco Is This A DIY Brick Job Or Should I Get A Contractor?

Is this a DIY brick job or should I get a contractor? - diy stucco

Forgive me, I asked this question yesterday, and left important details. My house is in S. California, at the age of 22 years and 90% stucco. You see, the developer installed 1 / 2 "stone (6 lines horizontal, 1 vertical, 8'x3 ') on the front of the house. I do not want to go, and many have been canceled - is terrible.
Is this a DIY job or should I become an entrepreneur? What should I expect from a contractor responsible?
