Record a video course on a given programming language

I need a 1 hour tutorial on several programming languages. 1 hour recording per language. Price per hour of recording: 40-70$. The bid must be in that range. Language requirement: English (fluent). You can use online resources to learn the language but the course should include different (can be similar) code from the resources. What I mean is content should be original. The course should have clear explanations for beginners with 95% code 5% theory. Each video must be 2-7 minutes long. First 5 minute video will be recorded before the the project to check if you apply. The course will be promoted and if students will like the course there will be possibility to work on 4-9 additional hours of content for the same or higher rate. Some of the programming languages we will work on are Prolog, Lisp, Sheme, Ada, Hack Logo D, and etc. Write in the proposal word 'table' if you have read the requirements. Thank you.
