Three points:
1-I THINK I would have progressed as did the OP. I have experienced similar situations and that was how I handled the matter.
2-I accessed four definitions of professional and I seem to fit the description, although I am considerably part time.
3-Rousseau stated what Bare "IS." Of that I have zero knowledge, but as to WAS, I am quite familiar. I completed my first shop for them in the spring of 2006; it was such a frustratingly unpleasant experience, Bare was the first MSC I terminated. When a male from their company contacted me a few yrs. later concerning a re-establishment of our relationship, I refused to discuss such a possibility. I have never, in the slightest, regretted my decision to sever the connection.
