Photoshop Expert for Realistic Photo Edits

I need an experienced **Photoshop/photo manipulation editor** to realistically edit several photos taken in my home office. The main task is to **add product/camera boxes into my existing photos** so they look like they were genuinely there when the photos were taken. For example: * In some photos, I want the supplied **camera/lens box image placed into my hands**, replacing the box I am currently holding. * In other photos, I want several supplied **camera/lens boxes added naturally around my home office**, such as on the desk, beside the printer, behind the laptop, or stacked nearby. * The boxes must match the **correct perspective, size, lighting, shadows, reflections, colour and image quality** of the original photo. * The final images must look completely natural and realistic, with no obvious signs that anything was added digitally. * I will provide the original home-office photos and the reference/product-box images. I need someone who is highly skilled in **realistic Photoshop compositing, perspective matching, object replacement, masking, lighting and shadows**. Please show examples of similar realistic photo-editing/compositing work you have completed.
