Alter product images for ecommerce website

Hello - I need the services of images editing professionals. The standard tasks for the images would involve - a) White background (in compliance with amazon guidelines for whitening) through clipping path I would presume b) Image centering (some images on the mannequin may be off by a couple of degrees to left or right. Would need help making them straight) c) Remove of mannequin (should be covered under background whitening) d) Image modification of polishing or whatever you need to do to make it professional Anticipated volumes - I expect the volumes to be conservatively 3-4 images per product. We anticipate an average of around 50-100 products each month. So would translate to possibly 200-300 images per 100 product lot. I'm attaching to this message sample photographs that I have taken. We are still playing around with lighting. So I'm attaching one that is dark background and one that has a reasonably better exposure to lightening for the white background. Please edit these 2 images to showcase your abilities to make them amazon ready. I believe amazon has basic requirements that images are at least 1200-1300 pixels on the longest side. If you are unwilling to invest time to showcase your capabilities with the attachments or anticipate me paying for your time on editing the 2 attachments, please do not bid. I would not consider you valuing your clients time. Please note that I'm looking for a longterm service provider who can grow with us. We are not a large firm.
