Welcome to the community Nivedita!
Thank you for sharing about your business. It sounds like you have already put in a lot of research.
Is there anyone who can help with marketing & distribution ideas?
Touchpoint has a new article: Why Print and Direct Mail are Still Vital to Small Business Marketing that talks about marketing, other than online advertising. Interesting article that you might read and consider.
Using both direct mail and online advertising would be a very good consideration.
