You're only zoomed in too 2%, you need to set your zoom at 100% or your document/work area is going to look tiny!
Thats your whole problem xD
Look in the bottom left corner and you'll see a 2% change that to 100% to see the real size =]
I found your real problem.
You're making your document 350inces by 110inches, you need to make it 350 pixels by 110 pixels.
Refer to the image posted in my previous post, it says 1440

pixels not inches by 900

pixels not inches.
