Hi Ginger, and thanks for contacting CTB,
First, I need to tell you that CTB does not make grants for funding. We are a knowledge resource for people at all levels of effort to improve their communities.
Having said that, I want to encourage you to look for information within out Table of Contents that may help you in several ways:
First, consider how to define and communicate the need for, and benefits of, your proposed project. You made a very good start of that in your message to us.
Second, consider who all might become local allies in carrying out our goal. Please don't misunderstand what I am about to say, but your goal is small, local, and specific enough that local residents, school parents, construction companies, or other donors may be quite willing to pitch in and "just do it" for the school kids. Don't overlook any Agricultural Extension Agent that may be available on your island to assist.
Third, please do review our chapter 42 on grant Writing. and the related took kit 14. You will find those by clicking on the Learn a Skill graphic, then on Table of Contents. Scroll down to Chapter 42 (you will also see the tool kit to the right) and open that chapter.
After you have reviewed that, we invite you to peruse any other relevant chapters that may help you on planning of recruiting community involvement.
Best wishes for a successful, hopefully local, project!
PS: After thinking about this some more, I assume you have cleared the project with school administration. Because you will be providing food to the school cafeteria for student consumption, you should also discuss your project with the local Public Health Department before proceeding. Food sanitation regulations may apply.
