AI Power Users: Create a vector file for me

I need an Adobe Illustrator Power User to create design files for me based on photographs of tile work that I will provide. The three files I give you will be .psd. Here is something similar to what I will provide: [login to view URL] Because the tiles in the photographs are very old, the pieces are not perfectly symmetrical; I will, however, expect your design to be perfectly symmetrical. If a shape is copied over and over (e.g. a star or a rectangle) I expect all the stars and rectangles to be the same shape and size, i.e. identical. Here are the deliverables: - the designs must be a perfect square 500px X 500px - the designs must be tile-able on all four sides (i.e. if you copy the image it must seamlessly interlock with a copy of itself on every side). - the file must have each color element in a separate layer - each layer will be named as the color it represents (blue, white, red, cyan, yellow, etc) - there shall be no visible seams - it shall be delivered in the form of a .ai file (Adobe Illustrator file) With your bid, please send me a link to examples of your own vector image work.
