English & French Localization Support

I’m looking for a freelancer who can turn my current project into a genuinely bilingual experience. The scope right now is simple: support two languages—English and French—without changing any of the core functionality that already works in the single-language version.

What I expect you to do
• Extract every user-facing string into clean, well-structured resource files.
• Provide accurate French translations for each string (natural, not machine-literal).
• Re-integrate the strings and add a language-switching mechanism that remembers the visitor’s choice.
• Hand over clear instructions so I can add a third language later if needed.

Acceptance criteria
• All static and dynamic text appears correctly in both English and French.
• No layout breaks or RTL artefacts (everything stays left-to-right).
• A single toggle or menu lets users change languages on any page/screen, with their selection persisting across sessions.
• Final delivery includes the updated source, compiled build (if applicable), and translation files.

If you’ve handled two- or three-language rollouts before and can point me to a live example, that will help me choose quickly.
