Football (Soccer) Stadium Graphics

On my website I have a way for users to upgrade each of their 4 stands 1 level at a time. I need a soccer pitch in the middle, with the 4 stands around it (obviously creating a whole rectangle) The stands should start of small and increase with each level. I would like it so if one stand is level 2 and 1 is level 3 that they don't look completely bizzare. There are 10 levels required. So 10 images (then cut the images into 5... 4 stands and the pitch which stays the same). I hope I've explained it well, if not, pease send me a message and I'll give more info. Many thanks
