Add categories to FAQ system

Looking for a developer to add categories to our FAQ system. Currently, we can set up FAQs on the admin panel, and these are then displayed on the FAQ page all together. I need you to add a section to the admin, where we can create categories, and then assign each FAQ to a category. The FAQ page should then display the questions sorted by category. There is one small issue: Our website is multilingual. This means, that we must be able to set up the Category name in all languages we are offering on the website. Offered languages are available on the database. This means, that you will need to work with category ID and display the correct language depending on the current site language. Once this is done, we need you to add the option to translate the FAQ questions and answers on the admin, too, and display the language as per the current site language. Need the same for the "Help" section, which is working in a similar way. I am willing to pay $30, and need this done today.
