I'm planning to start a temple tourism business.
1.Picking a Underrated temple place.
2.Providing a tourism package .
3.Promoting it in a best way using existing technology.
Suggest by commenting.
Underrated temples are good spot but I would say first create a fake rumor or same thing like that, so that it will create curiosity among others and likely they would might think of it. What you say about it..?
