We are a team of designers and developers with expertise and experience in Photoshop, HTML5, CSS3, PHP, AJAX, JQuery, Angular JS, XML, Wordpress, Joomla, Shopify, Bootstrap, CodeIgniter, Laravel, Google Map API and MySql.
We have delivered many Wordpress sites, including multilingual sites.
I have studied your requirement and the reference site. It is possible to add multiple domains (one for each language) using single dashboard by using WPML plugin. We prefer multilingual CMS version of WPML plugin that costs 79$. So you will need to purchase this and provide it to us.
We will need CPanel and Wordpress admin access for site.
I ensure a very thorough job and also support if you need changes / enhancements in future. I look forward to hearing from you and working on the project.
