Antique Print Framing

I'm selling framed antique prints and need help with a photo editing task.

Requirements:
- Take a picture of a framed piece I provide
- Use existing photos of unframed prints
- Digitally "frame" the prints in a simple matte black metal frame with a white border mat
- Provide images in appropriate sizes for each print

Ideal Skills and Experience:
- Proficiency in photo editing software (e.g., Photoshop)
- Attention to detail
- Experience with product photography or digital framing
