Tiny images for a virtual room

We need a professional graphic designer for our website. He should create images for our new project. At our site the user can design a virtual room. - All images should be saved as png or gif format - The background of all items is transparent - 15-20 percent of the images should be animated, but in an unobtrusive manner. The animations should be fitting the style of the objects displayed - Each image should be provided in normal and mirrored versions - If any shadows are visible, they have to be adjusted for the mirrored versions We need - 150 different backgrounds of the room. They can be designed with different colors, different wallpapers or different scenarios. The perspective is 3D. These are the only graphics that don’t have transparent pixels. The size has to be exactly 420x200 pixels. The following items have to be much smaller that the background, because the users will be able to place them anywhere in their rooms. They will be displayed on top of the background image. - 200 different furniture items (in different sizes or colors) - 150 different accessories - 100 different animals and pets - 150 different plants - 50 miscellaneous objects (just be creative :-) Our new site is similar to http://us.cyworld.com. The graphic designer should know what cyworld is, how it works and what you can do there.
