my husband is an electrician has been for 12 years HOWEVER hes not getting the best pay he could where?

are good places for him to look into to get better pay? we live in notheastern PA and we both work in New York. does anyone have any good websites to look at that offer electrician jobs. hes only making 20 an hour which is decent but not great. hes excellent and has letter after letter of recommnedations and hes friends with several electric inspectors. his boss loves him but wont pay him anymore because he think hes paid well. i think they take advantgage of him because hes only 31. but his boss and his previous bos have both said they would never let him go. SO WHATS THE DEAL?
