Craft Engaging Walking Tour Itineraries

We're building a catalog of walking-tour itineraries for ZenaWalk, a premium audio-guide app for Genoa, Italy. We need 5-6 complete itineraries, each a pedestrian route through the historic city center with 6-13 stops.

The work is split into 3 milestones, each covering all itineraries together:

Architecture — research real locations per theme, verify GPS coordinates and walking distances, build the stop sequence, and provide a source sheet (with links) for every historical/cultural fact you plan to use
Narrative — build the storyline connecting the stops for each itinerary, using only the facts verified in Milestone 1
Full written content — write all editorial fields for every stop, following a detailed schema we'll provide (hook, story, deep-dive, practical info, etc.)

Requirements:

Rigorous research skills — every fact must be backed by real, checkable sources; no invented details
Excellent English writing (narrative journalism quality, not generic tourist-guide language)
Familiarity with Genoa is a plus, not required, as long as every fact is properly sourced
You have full creative freedom on tone/voice — there's no fixed house style to match
