Enhance & Design 3 Coordinated A2 Photographic Travel Prints

I am looking for a designer/photo editor to finish a coordinated set of three photographic wall prints for my kitchen/dining room.
I already have the exact three photographs I want to use. I am not looking for new images to be generated or for the scenes to be redesigned.
The work required is:
• Assess the three supplied images and professionally enhance/upscale them as necessary so they are suitable for high-quality A2 printing.
• Preserve natural photographic detail and avoid an artificial or heavily AI-processed appearance.
• Apply a very subtle and consistent vintage photographic treatment across all three images. By vintage I mean slightly warmer, softer and more muted — not sepia, distressed, illustrated or heavily filtered.
• Preserve the attractive natural colours of the food and destinations, particularly the blues and greens.
• Create a consistent poster layout using a warm cream/off-white background/border, photograph centred, country title above and caption below.
• Ensure all three have identical proportions, spacing, typography treatment and overall colour grading so they look like one deliberately coordinated set.
The wording will be:
ESPAÑA
Buenas comidas, mejores momentos.
ITALIA
La dolce vita.
FRANCE
Bon appétit.
The prints are for a kitchen/dining room with warm cream/ivory, soft sage green, grey, natural warm wood and small black accents, and will be displayed together in natural oak-effect frames. The finished set therefore needs to complement this palette rather than being overly bright, cool or saturated.
I will also provide a fourth image showing a visual mock-up of how I envisage the three finished prints looking together on the wall. This is for layout/style reference only and is not an additional photograph requiring editing.
Final deliverables: three portrait A2, high-resolution, print-ready files suitable for professional printing. I would also like the final editable/source files if possible.
Please include in your proposal:
• Your fixed total price for all three prints
• Number of revision rounds included
• Expected turnaround time
• Examples of relevant photo-enhancement, print/poster or photographic design work from your existing portfolio
I am looking for a fixed-price agreement for the complete set rather than hourly billing.
