Building a Website as the Following : http://www.oxygenhotel.it/

Hello i am a Hotel owner and i want to build my website as this one :[login to view URL] , i like verymuch this website who is sell oriented and i want something similar , i want also the booking button( check for aviability ) with the date of arrival in hotel the date of departure and how many people as the one in the website who redirects you to my booking engine for the hotel in the case of oxygen hotel it directs you to their booking engine : who is this one : [login to view URL],A The thing i like the most in this website is the menu of reservation button that follows youwhile you are scrolling down . So i want abpsolutly something like this . I want also a web site responsible oriented to mobile/ tablet , seo oriented , with of course google analytics and social buttons and to be as fast as possible to load . So imagge optimasing is a must and link optimized also is a big deal . So you are the expert to this and i have full trust in You . This website is also in languange so we have to do it also in italian as a first language and other language . It has to be also able to recognise automaticly you location or the language of your brouser so it opens in that language. I like to be able also to work in the backoffice so i can change some article and add some post to the website . Please read full description and only if you are able to do all this make a bid , i will choose someone fast becouse i am in a hurry to finish this project before new years eve. So i want a website that will be a copy of this one in matter of design funcion and various things that they are insite. Thanks for You time Klement
