Android Video Tutorials Needed

We are in need of video tutorials on how to program for the Android. This will be placed on a subscription service website called MyCodeTeacher.com. We are looking for tutorials on small, useful projects for beginners to the android. We have someone working on the following videos: Lesson 1 - Getting Started [5-10 minutes] This lesson will talk about the tools needed for the android including the Android SDK Lesson 2 - Hello Worlds [5-10 minutes] Go over basic hello world tutorial Lesson 3 - Getting Used to the SDK [10-20 minutes] Talk about the important APIs or commonly used methods in the android. They should be useful to the beginning developer Lesson 4 - Buttons [10 minutes] Go over how to execute basic buttons. Lesson 5 - Listview [Undetermined] This should go over how to use the basic listview of the android as well as setting one up and basic "on tap, execute" commands. We'd like to expand on this foundation. We would like to pay $50/video. Please send a demo video as well as suggestions on the best foundation to continue off of this structure of beginner videos. Thank you!
