Recreate Display Ad Creatives -- 2

I already have a complete set of AI-generated display ads exported as JPEG/PNG. I now need those visuals rebuilt from scratch so every element sits on its own layer and can be tweaked later.

4 ad sizes (4 total images - 1 of each size):

300 x 250
728 x 90
160 x 600
320 x 50

Please deliver each banner at the original dimensions in two versions: a flattened, web-ready JPEG/PNG for immediate use and a fully layered working file (PSD or AI—your choice) so we can edit in the future.

Consistency with the reference ads, sharp image quality, and a quick turnaround are what matter most. The idea is that we get the same images back, but in the proper dimensions.
