Build a "Software presentation Website"

Hello guys, We have a product already on market, currently available at [login to view URL] As you can see, the website is not professional neither easy to read/follow/understand. We already have a new brand-name for the product ([login to view URL]) and we would need a new website for this product. Main aspects: * easy to navigate * SEO friendly * Google search friendly (minimization, etc) * fully responsive * possibility to translate in other languages (english as main language) I am basically relying on you to suggest the perfect approach for having this product's presentation pages a success. I personally don't care if the website will be a template for some CMS (wordpress or joomla or whatever) or built from scratch in PHP/HTML, as long as the product's presentation would be easy to understand and follow. What I need from the website (but i am open to changes): * a product description page (there's a website product, a windows app and also a mobile app, atm android only) * a page to describe the product's features, with call to actions and all that stuff. With screenshots (that one can make via using [login to view URL] and photo editing software) * a pricing page * a contact page (name, mail, phone, message, etc) * a page to show the current customers with possibility to add/edit/delete customers (logo + website + "a testimonial" + partner's name) * a blog (or news page) where customers can subscribe for receiving the updates. I intend to announce product updates and changes there so all old/new customers could be aware of what's new What else I will later link to this product are a ticketing solution and a WIKI for product's features. Any additional information you require, feel free to let me know.
