Adding muscle anatomy layers to an existing psd -revised

Hi, This is a pre-requisite project to a similar project which ran last week. I have an existing psd file (not attached) with 20 or so muscles defined and a further 26 missing ones which need to be added. It's basically a case of looking at the list to get the name eg. adductors, looking on [login to view URL] or similar to see where the muscles are and then colouring them in using a similar manner to the other layers (example of end result attached). I would estimate once you have the first one done and know what you are doing it would be 5 or 6 an hour with some ease Thanks Paul
