5x7 Photo Enlargement 60x40

I have a single 5×7 photo that I’d like turned into a crisp, print-ready 60×40 image for a poster-style framed display. Before it scales up, I need the file professionally sharpened to eliminate any blur, colours balanced with clean brightness and contrast, and a little retouching to remove or alter a few distracting elements in the background. I’m not fixed on whether we add subtle borders or crop in; I’d like to see what you think looks best once you inspect the original, so feel free to present a couple of options side-by-side for approval. Deliverables • High-resolution, print-ready file at 60×40 inches (minimum 300 DPI) in TIFF or layered PSD, plus a flattened JPEG for preview • Alternate crop or border version for comparison • A quick proof first so I can confirm the edits before you finalise the large file Please let me know your preferred turnaround time and any file-prep guidelines I should follow when I send the original scan.
