Photo Editing - People Additions & Background Changes

As a burgeoning photographer, I've amassed a substantial amount of images that need alterations. I'm seeking a capable photo editor, preferably with Photoshop expertise, for an immediate trial task. If successful, there's potential for ongoing collaboration on a vast amount of pictures. The task at hand involves two key changes to my photos: 1. Addition of a person: The person must be incorporated realistically, not as an obvious add-on or for comic effect. The ability to seamlessly blend elements to create convincing results is a must. 2. Background alteration: The current backgrounds are to be replaced with natural themes. Mastery in depicting outdoor settings convincingly is equally important. The ideal freelancer will have significant experience in Photoshop or similar photo editing software, with a portfolio exhibiting a strong capacity for realistic digital manipulation. Examples of past work involving the addition of people or altering of backgrounds will be particularly attractive. Deadlines are also crucial for me, so reliability and promptness are vital. I'm excited to start this creative collaboration - let's bring these images to life together!
