create a set of image ads for Google Display Advertising

Hello, We have a landing page for our website - [login to view URL] We have a set of ads we use for Google Adwords Display network (You can see the ad attached) which don't work too good for us. We need a native Chinese from mainland China only! Designers/copywriters who are fluent in Mandarin Chinese. Sorry... Not from Hong Kong, Not from Taiwan, Not Cantonese speakers... Only Chinese freelancers fluent in Mandarin Chinese. We need a new set of good ads with the basic design to our landing page, in all of these sizes: Vertical rectangle: 240 x 400 Mobile leaderboard: 320 x 50 Banner: 468 x 60 Leaderboard: 728 x 90 Square: 250 x 250 Small square: 200 x 200 Large rectangle: 336 x 280 Inline rectangle: 300 x 250 Skyscraper: 120 x 600 Wide skyscraper: 160 x 600 Half-page: 300 x 600 Large leaderboard: 970x90 Everyone want to bid, please do, but we will need to see a sample design on one of these sizes, and if we are satisfied with it we'll choose you and give you green light to start working on all the sizes. * If the project will be good and the ads will work better than our old ads (you can see attached here) - than we will want more sets of ads! Thanks! Good luck!
