Crop, resize, flatten or perspective product images - Repost - open to bidding

Hi, I am looking for a photoshop expert to retouch the raw images of items and make them usable on the web to sell. You can check the samples attached. [login to view URL], [login to view URL] and [login to view URL] are samples that are given in explanations below. [login to view URL] will be the type of photos you will get mostly. You have to crop the image to fit only the image first, then cut the background precisely and let the item stand out alone, sometime this will be difficult and must be made carefully to prevent item itself cut. And after the item is all alone, either use a white background or some gradient background, or just transparent png. This will depend on the item group and I will tell you specifically. As a final, you have to add a watermark I provide and resize the image to my needs and retouch the colors if you think the photo looks not lighted enough. But do not change the colors, as they photos have to reflect the same colors as reality. You can find [login to view URL] as a sample of this finished work attached. Finally, sometimes, I will need some items photos to be flattened. From perspective image taken originally, you will convert them into flattened bird view as in FLATTENED.JPG. I use photoshop for these but you are free to use anything you want, as long as you give me the good quality output. If I contact you about this, I will send you a sample pack of a few items and will ask you to edit them as a try-out. Please bid keeping this in mind. This is an ongoing project, not one time, I will send you photos as the need comes but as a start, I will have approximately 100 different items. So bid an hourly rate.
