Contacts in Guatemala, Nicaragua, or Colombia

Hi, I run a small non-profit that partners with in-country organizations and communities on clean water and sanitation projects, and I'm starting to look for my next project in either Guatemala, Nicaragua, or Colombia (currently working in Colombia). I'm trying to make contact with local organizations to partner with, and have had limited success hearing back from places I have emailed. Maybe this is due to Covid, who knows, but I just thought I'd ask and see if anyone had contacts in these countries? Thank you, Brian
