Alpha mask/ Bakground cut out for 13 images

The requirement for this job is to create alpha masks around 13 wood cabinets, masking out but NOT erasing the background. The deliverable needs to be a Photoshop file (.PSD) with layer alpha masks like my sample file ([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. Do not resize the images or attempt any color correction. One image has objects on top of the cabinet, but the rest do not. Once the job is awarded, I will supply the provider with a link to the 13 images and an http location for upload the completed images. Our Budget is $30. Once awarded, I need the images within 24 hours. Please do not bid if you cannot meet this deadline. We will put money in escrow AFTER you provide a sample that meets our requirement; i.e. a PSD masking out but NOT erasing the background with no resizing or color correction. 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. :) Kind Regards, chris
