Alpha mask/ Background cut out and Corrections for 18 images

REQUIREMENTS: The requirement for this job is to create alpha masks around some farm equipment assemblies in 18 (12-megapixel) images, masking out but NOT erasing the background. See the attached contact sheet jpgs to see the nature of the assemblies. Additionally, the images should be color corrected so that colors are consistent between images and colors from reflections (sky, clothing, etc.) need to be corrected. Bright highlights should be darkened. And smudges or other obvious imperfections, should be corrected. Lastly, in the images of the full assemblies, a soft drop shadow should be created on a separate layer to imply that the assembly is sitting on a white floor in an endless white studio. See the attached PDF called [login to view URL] for more clarification. Also, feel free to ask questions. DELIVERABLES: The deliverables need to be a Photoshop files (.PSD) that are compatible with Photoshop CS2 or earlier with layer alpha masks like the sample file found here: [login to view URL] These objects have mostly straight edges, but I want the masks to be accurate and clean with no halo of the background. Please do not resize the images. Once the job is awarded, I will supply the provider with a link to a zip file with the 18 images. BUDGET: $50 max SCHEDULE: Once awarded, I need all of the PSD files back within 24 hours. Please do not bid if you cannot meet this deadline. TERMS: We will put money in escrow AFTER you provide a sample that meets our requirement. If you demonstrate that you understand and can provide a quality cutout, we will put the payment in escrow. Once we receive the all of the images, we will release the escrow to your account. If you do not like these terms, then please do not bid on the project OR propose your terms. :) Thank you.
