Mine sees clients 4 days a week, from around noon to 8 pm.

He works alone in two offices, one in a countryish/suburban area, the other in the middle of a big city. I've seen him in both places. The suburban one is very simple, in an old house, and his city one is very sleek and expensive looking. He is very into style. I much prefer the simpler office, though the city one is objectively far more beautiful.
