Extract Artcover from 13,000 Mp3 Albums

Hi, I need a script or software or whatever to extract the artcover from 13,000 Mp3 albums (13,000 Mp3 Albums, Result = 13,000 artcovers). I need to extract only one artcover from each album and this picture must have in the filename the folowin info: Artis - Album (Year - Genre - Kbps ) Example: Pet Shop Boys - Behaviour (1990 - Synthpop - 192kbps) The artcover is inside of each album, all Mp3 collection include the Tags v1 and v2 for: Artists, Album, Year, Genre, etc. This script must resize all the output pictures to 500x500. If you guarantee to me that you have the solution I will escrow $30 meantime I test your script, if your script works at 100% I will deliver your money. Budget $30
