我的母语是英语、粤语(繁体中文)、普通话(简体中文)。我可以立刻开始。
I am a native speaker and fluent in English, Cantonese (Traditional Chinese characters) and Putonghua (Simplified Chinese characters).
============================================
It needs to make it clear that my minimum offer is USD$30 or total amount may need to negotiate since details of task list, such as, help for open account, translation, API development, etc., are not mentioned in the project description (I have some bad experience was trapped by budgeted bid for "tons" of requests to build a "ROME City).
============================================
I have completed this Taobao API with excellent review:
