Help me with my Green Screening!

[Moskis]

Hey! I am about to get my green screen and put it up on the wall behind me. It will be in a corner so I really need some smooth lighting but I'm unsure how I should place the lighting and which lamps to buy.

Here's a picture of my corner: imgur: the simple image sharer

How would you say I should light up that corner? I sit a bit close to it but I'm afraid that's my only option unless I throw out a couch and make more room. That wall is hideous so I'll probably repaint it green to make it my green screen so it wont have any "wrinkles".
