I want my own follow / like system

Faced with the difficulty in getting Brazilian followers and likes, I want my own system for own use.

I need the following freed functions:
Instagram: follow and like
Facebook: follow, like status, like pages, rate pages

If possible, create a filter to target people in the database.


How much would this system cost me?
And what is the best source for getting these people to the database?


Sorry for bad English, I'm using the translator.
