Alter some Images

I have three png images that have 2-3 shapes and elements that i need masked and put on their own layer. Winning photoshopper will most likely need to have a pen tablet (wacom or simiar) to do an excellent job. This Job is for 3 hours of masking work and if done quickly & well, there is potential for more. These need to be done today, so please only bid if you can process it right away. I can not post sample images as they are not for public view. They are not simple masks, but they are not difficult either. Not as hard as masking hair, but not as easy as circles and shapes. Most of the masking will need to be done by hand, erasing the background around the elements. They are all soilds and have clear defined edges. Please show masking samples so I can make sure you can deliver the quality needed. Please do not post up generic portfolios and non-related work. Thank you for looking at this job.
