Professional Product Photography

I’m looking for any photo editor who can just straighten a few things up with photos I have already taken. I’m an intern and one of my tasks was product photography, I’m a business major so I tried my best, but don’t think they’re quite at par level. There’s only about 15-20 photos and I’ve already whited out most of the backgrounds.

I’ve already cleared the backgrounds to make them white, I just have no idea how to make the two pieces aline together, and better the lighting.

Theres only about 15-20 photos, I can send them as soon as you’re able to edit them. Thank you to whomever can assist me.
