Its best to work with deamon on a ceremonial level first. They aren't going to just stand around and shake your hand astrally.
Most spiritual beings that people call "demons" are low spirits that are just malicious, they're not really evil entities, just spirits that are mean, angry, and look to destroy. Some are nature spirits. If you look into folklore, most cultures depicted dark nature spirits of various names that look pretty darn creepy, and they were feared, given offerings in hopes they would find the offerer as useful (not harming them) not really befriended in any way. Such beings are not to be trusted.
Daemons on the other hand are lesser gods, higher beings in short. If you get a good relationship going with one ceremonially (in ritual) you can then choose to travel to meet one if they agree.
