Let us try to do the research for the first country, Argentina. And then, if everything will be okay, we will move on to the other countries.
I will pay for 10 hours for Argentina, because this is the one in which I am interested the most and we need to spend more time on it.
For other countries, I will pay for 8 hours for each.
I am not in a hurry with any deadline, so I will create a 5 days milestone for each country/8-10 hours of research.
I will not be accessible between Dec, 17 th and January, 5th.
