20 icons needed in same style as Yahoo Messenger Icons

I need 20 small icons created in the same style as the yahoo messenger icons. I have attached a picture to show just what I mean. To give you an idea of size, 12 have to fit across in an area approximately 600 pixels wide. With a little space between each one. The winning bidder will draw 2 sample icons. One would be a disco ball, the other would be a textbook(like a book students would study from) open. The text book, althouh very small ofcourse, should like there is some text written on it. Please send me samples if interested and I will pick the best. That is all. If you do submit a sample and I don't pick you, I know thanks doesn't mean much, but I do appreciate it, so thank you.
