I need a background replaced realistically in 2 photos

My project is to have a realistic background replaced in two photos. The current background is indoors. I would like a specific place to replace the background, such as a location or scene. Additionally, I will need significant retouching and editing to the photos in order to match the new background. I'm looking for an experienced freelancer who can take my photos and make them look professional, while making sure that the subject's features are not affected by the retouching process. The freelancer should also have experience with replacing backgrounds with an eye for realistic perspectives and angles.
