Hi , I do not think any developer would be willing to do this.
This is because there are hardly any Indian developers in this forum.
And developers from other countries , most likely would not like to invest in something which they would not be able to use.
Yeah , there is one Indian whom I and the world knows... HAKA (Epic Dev.)
I guess , you'll have to read a tutorial or something and do it on your own.
P.S - Even I wanted "Hindi" language... But I doubt anyone will do it. Will have to figure it out myself. Just didn't get the time to look for it. :P
