Create masked Photoshop images for 11 PNGs

Design details: I have 11 PNGs that need a mask created for each one. There is an interactive demo here: http://gametest.mobi/maskwork/ which includes the source files and details about exactly what is required.

I am on a very tight deadline and need you to be able to start immediately, and deliver the files as you complete them - with the final one being no more than 24 hours from now. You will deliver 11 PSD files, one per image. Please see the web site above for examples + details.
