We are a bilingual magazine publisher in Chongqing, China. We need an app to create and upload digital version to mobiles for Chinese and foreign readers in Chongqing. Thus：
1. Create and upload digital magazines (in PS mode now).
2. Inter-communicate with readers (forum, note, remark etc.)
3. readers can upload their pics and files to us too.
Can you do this? How much will it cost？
