There’s many reputable builders the folks on here talk about. Do a search for contacts that are in thread posts. Depending on where your at and how busy they are I’m sure you’ll find one. I’m going solo on my AV470 rebuild to 520 cause most in SoFlo are way busy. Would rather have someone who knows do the short block work but here I am gonna learn and go slow I guess. But in central Fl there are many.
