Often that is the only information we are given at the initial enquiry.
Well there is so much more information that we need to be able to quote.
Firstly which voice artist would you like?
We'll need the actual script (not just a word count.)
Will this be a wild recording or do we need to fit the voiceover to your video ("sync" or "voice to picture")?
Recording to picture takes much longer and therefore costs more.
Do we just need to send the voiceover artist to Soho (or another third party studio) - and you pay for the studio? Or would you like us to record here?
And most importantly:
Where will the voiceover be used?
Will it be a corporate voiceover (used internally for training or an intranet)? Initially we are often told its a corporate voiceover but it later transpires it will also be used on the web.
Will it be used on the internet? If so on which websites? Will it be on any Social Media sites?
Will it be used on TV? If so which TV stations, for how long and what are the TVRs of the voiceover (usage/repeat fees)?
So you see its a bit more complicated than "How much?"
