Explainer Video

Hi there, we're looking for an explainer video for our new service. A storyboard has been created and we're expecting the video to run for between 1 minute thirty seconds, and 2 minutes.

A previous video was made elsewhere, but this was unsatisfactory - however parts of that video could be used?

I'm looking for a video experience like this one from GoDaddy:
https://www.youtube.com/watch?v=r3Em3muSVus

A large portion of the video footage, will be of the website being used (i.e. scrolling up/down seeing certain panels, etc).

I will need:
- a female voiceover
- background music
- number of revisions permitted

Can you let me know asap.

*** Required Timeframe: 7 days
*** Budget: £750 max
*** Your Location: UK preferred!

Thanks,
Matt.
