Beautifying and retouching photos

I want to modify a couple of photos for online sales. I need 5 different transparent in png photos high-quality 2k x 2k pixels.

My request is not just to remove the background but to beautify the photos to look attractive, as exactly shown in samples.

I will send you a bunch of photos in jpg and dng to choose freely from.
I have other products as well, so I am looking for one designer to rely on for all of my work.
Please let me know the estimated time to complete the task.

Attached here are some as-is photos, and a samples of required.
Regards
