Hi...first you can start by word of mouth, selling in your apartment, nearby areas, to friends and family, etc. Then you can create whats app and FB groups.
Is it not sales tax equally shared between cental and state government levied at the point of sale? Secondlu do you know in which market there is demand for silk thread bangles? Do you have any special information, know-how about making this type of bangles? Is the product ibid is community oriented?
Create an Instagram page with interesting reels and posts.. Lot of female entrepreneurs doing this in Insta platform.. Just go through their profile pages... you may get an idea...
Years over five gone by and so I Trust you have found huge markets nationally and internationally. I would suggest you to post the photographs of your product here which might get better visibility globally and with suitable text about speciality of this product. In case GI tag already obtained that fact may also be reproduced here. Wish you Godspeed In your enterprising endeavour. Regards.
