High-Resolution Photo Manipulation

I need a skilled photo editor to add the groom from one high-resolution image (300 dpi or higher) into another group shot. I want the groom specifically positioned next to the bride (on the bride's right) in the group photo. There's no need for color correction or enhancement, just impeccable photo editing to ensure a seamless addition of the groom. The final product should look natural, as if the groom was present during the original photo shoot. Skills in Adobe Photoshop or similar editing software are essential. Experience in detailed photo manipulation is highly preferred.
