POD Paperback Cover Resizing Expert Needed

Hello, I need help resizing the cover of my POD paperback as per the advice below from KDP. Are there any expert book cover consultants at Freelancer? Thanks John Cover Resize the background or image on your front cover so that it extends 0.125” (3.2 mm) beyond the trim line. All covers must be sized for bleed, which means you need to add an extra 0.125" (3.2 mm) along the top, bottom, and sides of your cover file. Once you have increased the size of your cover, extend any images or backgrounds that you want to reach all the way to the edge of the page 0.125” (3.2 mm) beyond the trim line. This prevents manufacturing issues when the cover is trimmed to size.
