First congratulation for opened a computer institute.
Below mention some tips for advertising -
1. Print media is still widely used in advertising. Brochures, flyers, pamphlets, catalogs, and posters are just a few examples. Most importantly, they exist in places where electronic media cannot.
2. SEO is still widely used in online advertising. B2B listing, submit local classifieds submission (Quikr, OLX, JustDial etc..)
3. Do some SMO (Social media optimization) submission like - Facebook, Twitter
Good luck friend - may be it's helpful.
Thanks
