Guideline for contacting publisher

I wonder why you think it would be best for you to have a publisher? Nowadays where it fortunately gets easier ans easier for indies (independent = no publisher) to release a game with steam etc, why would anyone still want to have a publisher? If you are new to the scene and have an interesting game which is something “new”, you most likely wont find any nice publisher who lets you create the game you want (and pays you for it) without interfering too much.
