Nextjs 14 add i18n with language selector on footer

I am looking for a developer who can add i18n functionality to my Nextjs 14 project. The main requirement is to have a language selector on the footer that displays the available languages. The selected language should be remembered for future visits.

Ideal skills and experience:
- Proficiency in Nextjs 14
- Experience with i18n implementation
- Knowledge of front-end development and designing a language selector
- Familiarity with storing and retrieving language preferences for future visits

Languages to be included in the language selector are English and Spanish. The content should be automatically translated based on the selected language. The developer should ensure a seamless user experience with smooth language switching.

I have already added in next.config.js

i18n: {
locales: ['en', 'es'],
defaultLocale: 'es'
}
