Multilingual WordPress Website for Healing Business

I am looking for an experienced WordPress developer to build a professional multilingual website for my personal healing business.

I am a one-person business offering 1:1 healing sessions, and in the future retreats and also workshops/trainings for people who want to learn more in this field. The website should feel calm, trustworthy, warm, clear, and professional. It should not feel too commercial, loud, or overloaded. The goal is not to attract everyone, but to speak clearly to the right people who are genuinely interested in deep personal healing, retreats, and conscious inner work.
I already have the domain/website connected with IONOS. My texts are already prepared. The website needs to be created in 3 languages and must be easy for me to edit and update myself afterwards.

I am looking for someone who has a good sense for websites in the fields of wellness, healing, retreats, coaching, therapy, spirituality, or personal development. I want the website to feel personal, authentic, and high quality. Since I work directly with people in a sensitive field, trust is very important. The design should support that. Please do not apply if your style is mainly corporate, aggressive sales pages, or generic template websites.

Requirements:
Build the website in WordPress
Create a calm, professional, modern, and trustworthy design
Set up 3 language versions with a clear and correct language structure
Make sure each language version has its own proper URL structure
Make sure the website works perfectly on desktop, tablet, and mobile
Set up basic SEO so people can find me through specific keywords
Prepare SEO page titles, meta descriptions, headings, image alt texts, and clean URLs
Build the site in a way that I can easily update texts, images, retreats, workshops, and other content myself afterwards

Connect or configure everything correctly with IONOS if needed
Optimize the website for loading speed and basic technical performance
Set up contact forms or inquiry forms
Make the website visually coherent across all 3 languages
Provide a short handover or tutorial showing me how to update the website myself


Please only apply if you have experience with:
WordPress
multilingual websites
SEO
responsive design for mobile and tablet
personal brand websites
wellness, healing, retreat, coaching, therapy, spirituality, or personal development websites
client handover, so I can manage the website myself afterwards

In your application, please answer these questions:
Which WordPress editor or system would you use so I can edit the website myself later?
Which multilingual system would you use and why?
How would you structure the 3 language versions?
How will you make sure the website is SEO-friendly?
How will you make sure the website works well on phone and tablet?
How will I be able to update texts, retreats, workshops, and images myself afterwards?
Can you work with a separate WordPress/hosting user account instead of needing my personal login?
Can you provide a short tutorial or handover video at the end?
Please send examples of similar websites you have built.
Please explain shortly how you would approach this project.

I prefer to work with milestones. The final payment will be released after the website is fully working, tested on mobile/tablet/desktop, and I understand how to update it myself.
