i've used someone on Keen by the name of Yona - Expert Healer. i can't tell if he is full of it or actually doing something. all of his "healings" are specialized. he'll ask you like what you want off of his menu. i don't know if he can do a 3rd party, and again, i really don't know if he's legit.. and i've used him a couple of times now. i probably wouldn't again.
otherwise, i agree about Reiki. you can also find someone who does distant Reiki, and the person doesn't have to be in the same room.
you can also burn a white candle, or place one in a church, if there is one near you. and just pray in front of it for the person or send it good thoughts and energy.
