FW-Clothing Deep etched off mannequin from grey background.

I require a total of 74 digital images (provided as Canon RAW files or JPEG) to be deep etched (dresses and garments on a mannequin removed from a grey background. The clothing would be the hero, the mannequin would also be removed from the image. I will be looking for no missing edges or leftover background, or colour cast. I need only super minimal contrast adjustments, nothing too major, as the whites start to look grey and dirty instead of fresh and the images have already been shot to the standard the client is happy with, they don't need to be modified. Approximately 4 images may need to be slightly lightened/darkened minimally as per instruction in further detail. Colours need to be left as they are, no enhancements such as saturation etc unless otherwise specified. There are approximately 5 images that a small smudge on the garment may need to be removed. I require the background to be changed to white as specified web usage white, not regular RGB white which can look funny on web. The files will be used for an online webstore with a zoom function so need to have suitable quality. The files will also be used on a large monitor to display the images. The garments need to be placed within a white space 500pix wide x 800pix high. With a good amount of space but not too much. Example image can be supplied upon request. I need all files provided as jpegs: 1500pix wide by 2400pix high and 500pix wide x 800pix high. Some shots require the mannequin to be slightly tilted so as to be upright within the frame. It's pretty straightforward work but I want someone who is meticulous and cares about what they do. Please let me know what cost you estimate for 74 images and the estimated turnaround of this job. Thanks for your time.
