Hello
I can't give you a proper quote until I have a closer look at your app, and see what's involved.
But I have plenty of experience at producing videos like this. Please check the examples in my portfolio, and get back to me if you are interested.
Regards,
Sid Whiting
Please note that I check this computer on a regular basis, but I’m not sitting at it continuously. So, if I don’t respond immediately to your message, don’t worry – I will respond before too long.
Also, I am on GMT +8 time in Australia. While I keep reasonably “normal” hours, I also usually check for messages once during our “small hours”.
