Hello there!
I'm a graphic designer who has been using Photoshop for almost 7 years now. Removing background from images is part of my everyday job, so I have a lot of experience.
The level of difficulty and the time it takes varies from image to image, what are the photos about? this kind of job can get done in just a day, but I'd like to see the pictures first, or at least some of them.
Also, which format do you want the pictures to be delivered in? I'll send them in PNG unless you need a different one.
I'll attach some of the work I've done before removing backgrounds from images.
If there's any other information that I need to be aware of before starting, let me know.
