Seamless Photo Text Correction

I have a photo that contains text I need changed. I’ll supply the exact new wording; your job is to replace the existing words so convincingly that no one can tell an edit was made. That means:

• Match the original font, size, colour, spacing and any subtle effects (shadows, perspective, texture).
• Keep the rest of the image untouched and artefact-free.
• Deliver a high-resolution JPEG/PNG plus the layered source file (PSD or similar) so I can make tweaks later if needed.

Strong Photoshop (or equivalent) retouching skills and an eye for detail are essential—this is all about perfect integration.
