Joomla Multilingual Website or GitHub Translation Integration

We are looking for an experienced Joomla developer to help us establish an efficient translation workflow for our website, which needs to support six languages (English, French, German, Italian, Russian, Spanish). The objective is to simplify the management, updating and publication of translated website content. Scope of work: Review our existing Joomla website and multilingual configuration. Assess whether GitHub integration is the most appropriate solution. Recommend a user-friendly translation management workflow. Configure the necessary integration and automation, where appropriate. Ensure that translations can be reviewed and updated without requiring ongoing developer assistance. Provide brief documentation and training for website administrators. We are looking for a reliable, cost-effective and maintainable solution. Please provide an estimated timeline, budget and examples of similar Joomla multilingual projects you have completed.
