Hey man, I am really interested in writing blogs for you. I grew up in Bangalore and went to a good school, you won't find any grammatical errors as such in my writing. I also visited your website, if you want me to write one for each of those topics, I will, and that's not going to take more than 3 days, if it's just one topic however, I can deliver in a single day.
Looking forward to working with you :)
