Remove backgrounds and add rop shadows on products images

I have 44 images of shoes that need the background removed. Most of the images also need a drop shadow added to add some definition once the background is removed (the only ones that don't, would be ones of the soles of the shoes. The images are pretty self explanatory). This I will leave to your discretion. I have files in both Hi RES JPG or NEF format. I also have 16 images of shoes that have had the background removed, these I would like to have a drop shadow added to them, again, where appropriate, and again this I will leave to your discretion. Also all images need to be scaled to 1000px x 1000px, any imperfections in the suede removed and the products straightened or rotated slightly if necessary to look like they are resting on a flat surface, again where appropriate. I have attached examples of both types of images, so you can see the quality of the images you will be working with and can quote accordingly. The image titled Ugg Boot is an example of the sort of finish we are after. This will be ongoing work as the shoe company is always updating their stock and looking for an ongoing relationship with a reliable and professional photo editor. Thanks!
