Enhance Conference Group Photo with Extra Participants

I need a freelancer with a keen eye for detail and proficiency in Photoshop or similar tools. The task is to add more random people to a conference group photo. These extra individuals should be seated with laptops, as per the theme of the conference. The final images should look realistic and blend seamlessly with the original photo.

Key Requirements:
- Adding extra people based on the gaps in the photo
- Placing them anywhere with visible space, ensuring a natural distribution
- Ensuring the additional individuals have a similar appearance to those already in the photo, while also introducing a level of diversity.
- enhance quality of existing pictures if possible

Ideal Skills:
- Expert level in Photoshop or equivalent software
- Strong understanding of visual realism
- Experience in photo manipulation and enhancement
- Ability to create a diverse yet cohesive group

Please note, the additional people should be similar to the existing ones in terms of general appearance, but there should also be a mix of diverse appearances. The final photo should maintain a professional tone, with the inserted individuals all dressed in professional attire. Please DM for the photos.
Keep the images confidential.
