Remove background to pictures

I'm looking for someone with experience to remove the background to some products pictures. The background removal must be seamless! It must not remove parts of the product or look low quality in any way: the products must remain INTACT, just remove the background. This is an easy job for someone who is experienced in image editing and knows what they are doing. Please only bid if you can get this done within 24 hours and please send sample background removal work. Attached please find the folder with the 75 images that need the background removal. Thanks!
