Test mobile prototype

We have an app (audiobooks and ebooks) at Android. We want to check how the new users' interaction occurring when they start using the app.

To conduct the test, we need to make a video call for about 25 minutes where you'll need to share your screen using Skype.
* Sharing the screen is needed because we want to see how you are using and interacting with the app.
The session will be recorded for analysis purposes and will not be shared with anyone outside of the company.
After using the app, we will have some follow up questions regarding the experience.

Our budget is $10 per interview and we need to do it with 5 to 10 users.

It is a fun and quick task and no high technical prior experience is required. If you're interested in audiobooks that will be plus merit :)
Hight internet speed is required for this task.
