Beautiful! A sanctuary is definitely what we plan to visit. I did think only of the elephant ones though. I believe that it's much better experience that "circus" animals and even better when we can also help.
Regarding startups, I recommend to read my book - https://www.amazon.com/dp/8097265915/. The I currently run a promotion and have the Kindle version for $1.19. It will definitely help you answer these questions.
If you have any particular questions after reading the book, I'd be happy to answer them.
@rina.tours.world I wanted to let you know that I've already started the "Startup Basics with Milan" series and published the first post - https://steemit.com/startups/@milansteskal/startup-basics-with-milan-1-introduction.
