Photos clipping path

Its me again, i have a new project for you. Project Description: I have various photos of items like the others I have sent you. Sunglasses, some jewellery, clothes, shoes etc Most of them very easy, few of them more difficult. I want you to only make a clipping path and resend me the photos as jpg, as they are. No cropping resizing or any other adjustment or retouch. No whitening background either. Jpg with clipping path is necessary, no png. Please help me how to make a "per hour hire" I think it is less cost for me because of freelance site fees. I will have some photos for you every month, it might be 20 pics, might be 80. The customer doesn't pay much, max I can give you is 0.8 us dollars per photo. How can I fix the per hour thing so that I will be within budget? I will upload the photos in about an hour. Thank you.
