All spells are not easy. Its your level of skill which makes it hard.
And summoning a servant I would say is a bit rude to the entity you are trying to contact. And an entity in anyway is not your servant. All entities deserve respect.
I would meditate to a chosen entity, spirit, demon whichever to occompany you in your studies, but I only recommend this if you know the basics!
Grounding circling etc the site has a section for that. You need to understand that that an entity is probably not going to respond if asked by force.
I would learn what familiar or companion you want first and learn from there but atleast know go by the basics
