Complete Chrome extension Course.

I want to build a course on Chrome extensions. The course will be video content from basics to advance level. I need a well experienced Chrome Developer for this Course. Please answer the following question before placing the bid. 1-How much is your experience with Chrome Extensions? 2-Did you ever record a video before? 3-How many extensions have to built before and what's their type? (Explain in details) 4-How is your English accent? (The course will be in English language only) 5-Did you teach before? 6-How long you think you need for the complete course and how much you will charge (Please remember I need a fix budget not hourly) I am looking forward to see the proposals. Thanks and regards.
