Chinese/English speaking SEO/designer for question answer

SKILLS REQUIRED SEARCH ENGINE OPTIMISATION DREAMWEAVER MARKETING SKILLS SPEAK GOOD ENGLISH I have an English website relating to car rental in Queensland Australia. We service the Gold Coast and Brisbane. The Gold coast is holiday destination My website is [login to view URL] I want to make a Chinese version of the web site, and get it ranking on [login to view URL] Effectively use same content as the English version, just change all to Chinese including title tags, meta tags , meta content etc all stuff changed to Chinese so it picks up on the Chinese search engine, mainly targeting baidu. I was thinking rather than using a new domain to host the new site I would link off the existing English site using sub domain so that I can leverage of the domain authority the site already has. So have banner on front page of English version site linking to Chinese version using sub domain like [login to view URL] [login to view URL] That domain name then becomes the home page. Rather than trying to target all keywords from that home page I will use additional sub pages from that domain for each location, the same as the English version with all the same pages like vehicles for hire, contact us, terms and conditions, locations, etc Except all in Chinese, like [login to view URL] will target all key words relating to gold coast car hire etc I not sure that I will need to create any back links in order to get high rankings or not , or whether the strong domain authority will be sufficient, I will need advice on that Also want to try sponsored links on Baidu search engines as well so I can get instant ranking position to try market out I also want advice on whether you think the Chinese will book directly through the search engines or whether there are better methods of getting business from the Chinese travellers wanting to holiday in Queensland particularly the gold coast Meaning perhaps Chinese travellers rather use agencies like travel agents or travel sites, need to know how ordinary Chinese people would go about booking a holiday, in particular booking a rental car. If there is good market for our product then we will want pernament contact and ongoing work to manage our chineese market
