Dear Employer
I have been in the web development industry for 4 years and such jobs are my daily practice. This is my first time on this site and hence you can see that I do not have any ratings/testimonials to show you, that's why I will do this job at such a small price.
Why do you need the mp3 version of the youtube video? You can control the youtube player.
I have already done a simple version of this concept.
I am sure that a webpage can't wake a computer from sleep.
I will comment the code, but if you have any questions I will help you.
I can assure you that if you work with me once, you will always work with me for these kind of projects.
