I need 14 product photos creating for use as promotional photos

I have taken several pictures of the same person in the same place so the best can be chosen to be edited. These photos are for a rifle brand which we are importing. We will be doing an actual photo shoot very soon but needed something fast.
They have been taken on an iPhone 12 max in raw format. These need to show the product and brand clearly, backgrounds can be removed or changed, anything you think to ensure its usable to highlight the rife or give a dramatic effect.

Below is two examples of the images.
