I need a freelancer who can help "tune" and "tone" up my client's speaking skill

Hi,
I need a freelancer who can help tune up my client's urdu speaking skill.
My client has ample vocabularies, has been a decent hindi speaker, and highly interested in the literature, but sometimes misses precise speaking "tune" and "tone" in urdu.
Please make a reasonable quote.
Only serious bidders please.
Thanks.
