Photoshop 11 images

I have 11 high res images (about 2-3mb each) that need to be photoshopped.
Images are of water skis.
All images require the background and any shadows to be removed and saved in png file format. Only the ski should remain.
Some images also require to have edges of the skis cleaned up and texturing on the surface of the ski to be smoothed.
Due to confidentiality of the product, I can only supply high res images once you have expressed interest. You can supply a final price once you have reviewed.
Need this by mid week.
Thanks
