Photo editing - URGENT!

I have approximately 130 photos of teddies and floral arrangements to be used for an online flower store. All images were taken against a white back drop, and need to be completely extracted to have a pure 100% white background. No shadows. No spots. All images need to be saved as a separate layer in a photoshop document. It is not sufficient to use the smart highlighter, and I will not accept any rough edges, or missing pixels that have been carelessly deleted. Everything must be done perfectly. This work should take around 10-16 hours for a competent photoshop user, and due to a very tight deadline, this is all the time that I can allocate for the project. All images must be edited and uploaded within 20 hours of accepting the project. ** DO NOT BID UNLESS YOU CAN DO THIS WORK PROPERLY. THE SUCCESSFUL BIDDER WILL NEED TO HAVE EDITED THE 2 ATTACHED SAMPLE IMAGES TO SHOW THEIR LEVEL OF SERVICE, QUALITY & SKILL. IF YOU CAN'T COMPLETE THE WORK WITHIN THE REQUESTED TIME FRAME, PLEASE DO NOT WASTE MY TIME OR YOURS. I WILL NOT WAIT FOR ANY WORK SUBMITTED AFTER THE DEADLINE. I WILL SIMPLY RE-LIST THE PROJECT AND NO PAYMENT WILL BE MADE.
