How to learn 2D Game Art?

Biiiig question!

I’m since 2009 a hobby programmer.
Now I want to make a game, so long so good.

But the problem is I can actually develop the game,
but I have 0% knowledge of 2D Game Art.

It is a Simulator like Game Dev Tycoon, but has an different setting (has nothing to do with Games).

Did you know a way how to learn fast & simple 2D Game Art? Or did you know a good place where I can cheap hire some freelancers for this job.

(sorry for my English, this is not my native language)

Hope for some replys,
