Video Editing for Small Crowd

I'm looking for a skilled video editor to add 2-3 audience members (just the backs of their heads) into my video to create the appearance of a small crowd. The setting is an indoor auditorium.

Requirements:
- Realistic editing style
- Source appropriate photos of adults online
- Prefer audience members with some movement

Ideal Skills and Experience:
- Proficiency in video editing software
- Experience with realistic photo integration
- Attention to detail and creativity

Thank you in advance!
