Build an e-learning web-service with CMS, LMS, cloud, sharing, and SNS functions.

We are looking for a team of talented developers and designers who have experience to have built content-sharing web sites. Web service: - The site is an e-learning web-service for foreign language learners with CMS, LMS, cloud, sharing, and SNS functions. - Anyone can upload and share his/her lessons of video, voice, writings, using his/her own mother language, which can be valuable lessons for others who are learning the language. - He/she can be both a teacher of his/her own language and a student of foreign languages. - The lessons are roughly divided by 2 styles. Input lessons: learners take lessons uploaded by teachers, organized, based on levels and contents, which should be fun to take,entertained by gamification. Output lessons: learners can upload their videos, voices and writings, which are edited by native teachers. And this should be mutual activities. - Both up-loaded lessons have the limit on size, and that can be up-graded by some payment. - All the up-loaded contents should be automatically converted and displayed by each and every device and browser. (old browsers such as IE6 can be ignored) - Preferably, no-need to create an app for smart-phones. Just a favicon for smart-phones would be provided on the site. Design: - The main target device is the smart-phone size (1 column with variable-width). Based on this, 2-column pages for tablets and 3-column pages for PC should be supplementary made. - All the pages should be on flat and simple designs. - The interface is intuitively clear, using many icons, but the icons should not use words of any languages. - When an instruction is needed, then, it should be well-explained in words, which can be translated by us. - Because the site is shown in multi-languages, the basic site color should be white, light grey or light beige with grey or light black letters, in order to maintain its readability. - Ads should be naturally a part of pages. They should not be prominent nor flashy on the pages. - The total image of the site is “excitement of travels”.
