Although you asked for help with specific demons, I would like to add a relatively easy spell that can be used in addition to working with them.
If you work with candle magick you can easily put an idea into someones head. You only need a few spell items.
Purple Skull Candle
Commanding or Controlling Oil
Bend over powder
-High John Conquer Root
Small petition paper with desired result
Small witness sample/taglock
First carve the targets name into the top of the skull.
Then use a nail or something to carve out a small whole just big enough for the witness sample and put it in. Be sure to pack the wax back on top of it.
Then dress it with your oil and fix it to a fireproof base.
Next sprinkle the skull with your bend over powder.
Now anoint each corner and the center of your petition paper.
Go ahead and light your candle and burn your petition in the flames.
You can do this while evoking a particular demon or instead of evocation.
