Not to be a downer, but that's pretty expensive. I spent last week in [latam capital city] and met with 3 local outsourcing firms, down from 6 that I'd pre-screened by Zoom. I then reduced the list to 2 based on the co-founders of each being technical, and their solid recruiting practices. Both have offices which devs are free to come into (or work remotely), both pay salaries and offer benefits, both provide embedded developers with project managers in the background, both provide in house training and skills development. One charges $30/hr-$45/hr, one $40-$55, with the rate difference being based on the location of the devs (the cheaper range is 2 hours north of the metro area).

Both have accounts in the US which you can pay directly if you don't want to deal with wire transfers (though those also are easy). Both handle taxes.
