Ajax to make upload with indicator process

I want UPLOAD feature using Ajax and php including a progress indicator which must be placed below my current wimpy player. I want users to upload only mp3 and jpg files. If a user uploads an mp3 file, I want it to force the user to upload a jpg image for the mp3 song. (BOTH MP3 and jpg should be in the same folder.) I want the jpg image file default name to automatically be renamed and have or bare same name as the mp3 file. and lastly. PLEASE SEE ATTACHED FILE. My maximum is $40. Please bid if you can do it. Will pick you immediately. Thanks.
