2005 Prius codes c1256 c1391, recommendations for repair?

Hello All,

My 2005 Prius got the codes c1256 c1391, along with the VSC, ABS, and Brake on lights, which seems to indicate ABS Actuator problems based on what I've seen online. My local Toyota dealer recommended to replace the actuator for $3500!
Can someone recommend a good independent Toyota repair shop that can do this for less exorbitant pricing?
Location is Montgomery County, MD, along I-270 corridor. Thanks in advance.
