Jonathan, just visited your website. I see you've gotten several contributors for seed money you've received from various organizations to start your center.
Have you contacted folks who captive breed frogs for possible equipment donations (e.g. racks, humidifiers, containers, etc.)? I imagine shipping to Honduras may be cost prohibitive, but it may be worth a shot?
These types of projects need more exposure. Here is the direct link to Jonathan's website, which goes into detail which species they are specifically trying to conserve.
