I'll buck the trend and say "D". If you truly are quality, and have a known reputation, I say build upon that and set yourself apart from others. Gain even more education , i.e.Lab Day :-) hands on courses, and most of all become indispensable to your nearby accounts, as in custom shades, evaluating your work in the mouth, understanding cements, bonding etc. to be a resource for them.
On the other hand, if you are hurting for work, what the others here are suggesting are good points.
