Three-Photo Print Collage

I have three separate photographs that I would like merged into a single, professionally-finished composition suitable for high-quality printing. The end product should be large enough to hold detail at poster size, delivered in both a flattened CMYK TIFF (300 dpi) ready for the print shop and an editable layered PSD so I can make minor adjustments later if needed.

I’m flexible on the exact arrangement—side-by-side, stacked, or something more creative—so long as the final piece feels cohesive and balanced. Color correction, edge blending, and any subtle retouching required to make the images sit naturally together are part of the brief.

Please make sure:
• The combined file stays sharp at 300 dpi for at least an 18×24-inch print.
• All layers remain labeled and organized in the PSD.
• You include a short note on any fonts or effects used, in case text or graphic elements are added later.

If you’ve produced print-ready collages or composites before, feel free to mention it when you submit. A quick turnaround is appreciated, and I’ll supply the three source files as soon as we agree to proceed.

I need all the pictures of my family combined into one group photo. I put the pic of the girl in the red dress and her brother I put a pic of them in twice bc I don’t really want her in a prom dress in the group pic of them all so wasn’t sure what ones would be better to use. I also am giving this for a Mother’s Day gift
