When you change a casual form "~てくれる" to the polite form, you just change くれる to くれます while the -te form is not changed, right? It's quite the similar in this case. アドバイサーの方が仕事を見つけてくださいました is correct.
(お見つけになってくださいました is not incorrect, but sounds too polite. These types of honorifics are often used in business scene, or rather, used only in business scene.)
