But why don't you buy more of those centers if they are good and cheap ?
They are cheap because there are too many of them compared to the number of teams in need for them and capable of sustaining their salary.
They should naturally retire in large numbers and the problem would be solved but this process is impaired by NTs, people trying to speculate on their selling price and reckeless newbies.
You are an unhappy seller but soon a happy buyer.
