Recommend me a decent hub repair service. Please.

What does pitting mean? I recently got Lock 7 to service my rear wheel and on the receipt they wrote "not perfect - hub pitted". Does this mean the hub is on its way out?

what needs to be replaced?
no need to replace cones if they are smooth with no damage or pitting, if bb's are shiny and if theres no damage or pitting to the cups
replace bb's if there dull or damaged, damaged or pitting cones and i dont think you can replace a cup, a new hub would be called for

just de grease then re grease
