Hey how's it going? Since you live in the US the best site for parts is www.rockauto.com here's a search:

They list KYB at $ 49 a piece vs the $ 100 quoted by your mechanic, I know shipping is a bit extra but still cheaper than what you were quoted. I buy from here as often as i can even when I get hot with duties at the customs border
