Audio Player buttons for iPhone App

Design buttons for an audio player on an iPhone application. The buttons will work as a pop up feature in the app, so that user can audition audio files. I need 4 buttons, in a 3d effect style to match existing artwork, which will be provided. Dimensions and rough sketches of buttons will be provided. You must provide the buttons in .png format in line with Apple iPhone design standards, and also provide the .psd file. 4 buttons as follows: play pause cue audio download audio plus a simple close button (x) There is a tight deadline for this work, needed in 2 days. If you do not make the deadline i reserve the right to cancel and find another artist. There may be some additional simple graphics required, for which I will make an additional payment, to be negotiated. Thank you
