eazy photoshop project need it now......

I need someone to cut a background out of 4 pictures. They are pictures with a pretty basic background.... I need this done good! I want the image to look good over both a white and a black background so there can not be any extra pixels around the hair that will be visible... Im looking for professional quality..... I'm a designer that needs to complete 3 designs today that has no time to prep these photos. Show me previouse before and after images you have done or I can send you an image to prove yourself to me, I need this done now!!! If you cant do this now do not bid. The cheapest best quality work wins. Let me know what you can do for me. Thanks.
