Bismihi Ta'ala

We are not aware of any exorcists/Aamils. Alot of people claim to have such knowledge but one must be very careful when approaching them.
Alot of them charge a huge sum of money before they start their investigation.

Alot of innocent Muslims fall into the trap. Great caution must be practised in this aspect. On most occasions, there is nothing wrong with the afflicted person. He may be ill, which is from Allah, and can happen to any man, but an Aamil would say that somebody has done some magic on him.
I have come across Aamils who wrongly judged the condition of an individual and they almost died. There was nothing wrong with them spiritually. She had a brain tumour but the Aamil said somebody has done magic on her. Had she relied on his investigation, she would have died.

Allah knows best.
