Hey there, Would love to create the video for you. Here is a link to my portfolio.
( google.com/+MonkSanTheNocturnalMonk )...
Can you provide more details about the project and will you be providing the screenshots from your application?
I don't provide voice-over services, It'd be great if you could get it done by a professional voice-artist.
Open to discuss further.
Regards,
Sandeep
