Recording Voice For Videogame Need Some Advice

I´m looking to record some voices for a videogame.

Has anyone any experience? I contacted one “international” studio and they wanted $750 for each voice.
We need voices in Chinese,Japanese,English and we need “cool” male and female voices.

But we only need something like 20-30 words in each language so this seems quite expensive.
Though for a hollywood movie that would probably be ok.

What do you think?
How much does a professional studio charge per hour?
And what cost should could we expect to get a good voice actor.

maybe this , dunno … it might be good
