Family Photo Editing for Canvas

I need a family photo edited for a canvas print. The task involves removing one person from the photo and adding an arm to the person next to them.

I've included a photo with her arm, but if that one doesn't work, I have several others from this day that I can send. The person I want removed is the man on the right wearing the bright blue short sleeve shirt.

Key Requirements:
- Remove one person from the photo
- Seamlessly integrate with the existing background
- Add an arm to the adjacent person using other pictures where her arm is showing
- Ensure the final image is suitable for canvas printing

Ideal Skills:
- Proficiency in photo editing software (e.g., Adobe Photoshop)
- Experience in photo retouching and manipulation
- Attention to detail to ensure a seamless final product

The final photo is intended for canvas printing, so high-quality work is essential. Please ensure the background remains consistent and the added arm looks natural.

If this one works out, i will have several other images I want edited. Also, I am hoping the image quality will not be affected.
