first. what fortune telling do you need help with? it's a very broad question. do you mean you've done some type of fortune telling and need help with a couple cards/runes/whatever. or do you mean you need someone to read your fortune? if you need your fortune tell, what do you want to know? i suggest you give more detail and post in the fortune telling section of the forums.
second. again, what type of healing? for you, for someone else, with herbs, with energy, with crystals?
third. a cleansing followed by protection is usually the way to go. though i don't know about the devil as it is a concept, and i personally don't believe in someone in a red suit with horns and a hay fork. as with the previous options some more information would help [though unlike the previous two the answer can be provided easier] depending on the entity it might be harder, but basically you need to cleanse, start by having a purifying bath for yourself, then cleanse your house top to bottom with a purification brew and sage smudge [or other cleansing herbs] finally cast a protection spell on yourself and the home. daily meditation and shielding yourself is a good idea, as well as recasting the protection once a month or once a week depending on how strong the force is that's bothering you.
