Wordpress Developer for Law Firm

I got a website [login to view URL] with an envato template and need some customizations: I need to centralize "Submit your message" button in the Contact Form and change it to portuguese, also changing the contact form fields to Portuguese; I need to change the phone icon at the top to a golden whatsapp logo icon; I want to put a blog in the website for articles, the template has a default one, it should be easy. Also need to be added a “Blog” Button on the top of the page next to "Início", "Sobre" and "Contato"; I want to add dropdown boxes to show the areas the office works on. Also need to be added an “Áreas” Button on the top of the page next to "Início", "Blog", "Sobre" and "Contato"; I want to add a Professional Box “Equipe” in the main page, to display small info and a picture about the main lawyer of the firm. Also need to be added an “Equipe” Button; In the footer I want it to show my e-mail with a letter icon next to it, my phone number with a whatsapp logo icon next to it, as Address I want it to show only “Porto, Portugal” for now with a Pin icon next to it; I want to direct the user to be redirected to the corresponding paragraphs of the static page after he clicks on “Blog”, “Sobre”, “Áreas”, “Equipe” and “Contato”. I need to fix the mobile page that displays an “Order Now” box on the cover, that needs to be taken out; I want to make the Login button invisible for now. I want the website to remain as a static page, all the info must be in the main page. I got an example idea to show. I’m probably also going to need it after some easy coreldraw work on my stationery, like putting a whatsapp logo in my visit card and etc. I’ll talk about that after the website customization because I need to check all the changes I need for that yet.
