Hello Sir/Madam,
Myself is Sanjana Mitra, a bengali, born and brought up in Kolkata. I am out of Bengal since 2005, currently staying at Mumbai. As a bengali medium student, I know the basic of bengali grammer very well. Moreover, to make my junior team members well versed in spoken english I had followed such techniques and most of them have Hindi as their mother tongue.
I think I can understand and do your project successfully.
With regards,
Sanjana
