I need some sprite for a new "jewel"-type game

I am developing a new game and I need a set of 2D assets for it. The game will involve linking jewel-like objects (such as the ones in BEJEWLED, etc) Sample artwork which I like: https://www.dropbox.com/sh/q3ti9bl6016h5f2/MAtOzrKxyy I need to know the rate for such sprites and the availability of the artist. I will provide full project description after I receive portfolio link, rates and availability. Thank you very much,Robert
