Hello, we are looking for someone to edit our photographs for our antiques store advertisements on an ongoing/long term basis. Basic background removal to a clean, white background. Likely would be around 100 images per week. Images would be uploaded by me to a shared dropbox folder and then edited and uploaded back into the Dropbox folder by you. Please tell me approximately how many hours you would need to edit 100 images. Thank-you for your interest in our project.
