Hi,
it's indeed an ambitious plan
I can't really evaluate the feasibility
of crowdsourcing because I'm not from Brazil
but I suppose it will be
pretty challenging considering the economic difficulties the country is
experiencing nowadays.
Where the calculation fails IHMO is the salary of developers. From what
I heard from my Brazilian colleagues, there is no way to hire a full-
time developer for $440. To get at least a bit experienced software
developer, I think you need at least $2000 even in Brazil. Note that
the total cost is not only the net salary, but it also includes taxes,
social, health insurance and other employee-related expenses. In most
countries, the company's direct costs on an employee are at least twice
as much as what they receive in the end.
