You mean you can't make it in a week??!!
I could, some folks do i suppose, more like a production line than anything, but doesn't bode well for originality or quality imo. 
I can't work like that myself, too much of a massive compulsive obsessive type. Almost every single image and image state is zoomed to X3200 dozens of times before I might be finally happy with it, manipulating every shape's vector points to as close to perfection as I can get. (or photoshop will allow)
It is the only way to ensure pixels aren't hanging over a quarter or an eighth of a pixel.
This ensures zero blurriness at 100%.
It's not the fastest way of working, but to me, it's definitely the best.
