Automatic Multilingual Translation for WordPress Site

I'm seeking an expert who can install an automatic translation plugin on my French WordPress site. My goal is to have all existing content translated into a wide range of languages, with the capacity for future content to be automatically translated as well.

Requirements:
- Translate all current text posts into the following languages:
- German
- American English
- British English
- Arabic
- Bulgarian
- Simplified Chinese
- Traditional Chinese
- Korean
- Danish
- Spanish
- Estonian
- Finnish
- French
- Greek
- Hungarian
- Indonesian
- Italian
- Japanese
- Latvian
- Lithuanian
- Dutch
- Norwegian (Bokmål)
- Polish
- Portuguese
- Brazilian Portuguese
- Romanian
- Russian
- Slovak
- Slovenian
- Swedish
- Czech
- Turkish
- Ukrainian

- Ensure all future content is also automatically translated into these languages.

The ideal freelancer for this project should have extensive experience with WordPress and translation plugins. Since a specific plugin has not been preferred, your expertise in selecting the most efficient and effective one is crucial. The focus is solely on automatic translation, without the need for manual editing of translations.
