Yes there are plenty, or you could go an a merry jaunt through the etheric realms to Hell and very politely talk to one instead of arrogantly commanding one to come to you.
Do you honestly believe you can control something who is ancient? something that has knowledge beyond what your brain will ever comprehend?
Oh and for the immensely egotistical, define "evil." It is nothing but a point of view and a set of beliefs on what is right and wrong. Nothing is evil, to believe that because something doesn't fit in with what you call "good" does not in the slightest mean it is evil. So to call a higher entity "evil" is quite probably one of the most ignorant things anyone has ever said.
