Okay, so a lot of users (such as myself) are always in dire need for good posters made by other people since we lack the skills (lolz let's not deny it, there's a lot of us out there), so I'm gonna do God's work and share with you a good poster shop you can go to if you're looking for a poster. 

Willow Graphics Shop by ColourSynesthesia

It's super easy stuff for some really amazing art. Check out the samples!

If you're not sure simply because you have some questions, there's a Rules, Prices, and FAQ chapter you can check out as well!

Trust me guys, you won't regret it!!
