Edit the design of a Flyer

We created a flyer that looks pretty good but the images need to be edited because we are not good at it. Let's go through what we need on the front of the flyer on top is our logo, we will keep that, then follows a short text then images of 3 cars, you will need to edit images of Cadillac Escalade, Lincoln Navigator, and Chrysler 300. Those use to be 3 different pictures and will need a designer to edit them so it looks like they were made for this picture and delete the previous backgrounds that make them look worth. I attached the flyer.
