I applaud what your organization is trying to do. I too am troubled by food insecurity, not just abroad, but in our own US. I'm alarmed at climate change deniers and what that means for our future. I don't understand those who refuse to believe in evolution. Even if I'm not chosen as your freelancer, I hope you do good things.
All that being said, I believe I can deliver a brochure that you will be extremely pleased with. I have a college degree in management and spent almost 25 years working in the government sector. The last 15 years were at management and director level. I often had to produce the type of material you are requesting and understand, especially with a brochure format, that it must be compelling, concise and engaging.
I'd approach this first by doing more than the cursory review I just did of your website. I may ask for some sort of communication with key stakeholders in your group to gain more insight into your work. I can do that through either a written questionnaire or through on line chatting or messaging. If you have any other material not available on your website to help with my inspiration that would be great, too.
Lastly, although I don't have a professional design background, I have produced brochures and newsletters off template that looked nice and made my clients happy. I can insert your photos, tag lines, logos, etc. I won't say I can create a format from scratch, but there are a number of nice templates, if you want to go that route.
