Cost of Drupal SEO in New Delhi

Hi everybody,

I'm US-based developer, who created a pro bono website (Let's Go! India Tours) for a gentleman in India. I don't speak Hindi, so the language barrier is a huge problem. As a result, I'm now looking for someone local (New Delhi) to take over site maintenance (content updates, page additions, installing contrib. modules, etc) as well as SEO. This all puts me in an awkward position of going to English-language websites to look for an Indian developer/optimizer for my Indian client.

Can anyone provide a ballpark figure for an hourly rate (in RS) that my client can expect to pay for SEO, content updates, page additions, etc?
Also, I welcome any advice on how and where I can find affordable and local help for this gentleman.

Thank you in advance.
