Elementary School Booster Club Grant Writing (and research) Support

We are a non-profit group of volunteer parents who run a pretty well established Booster Club. Our school is a title-1 school where over 50% of our students are low-income and have qualified for government subsidized support. The Booster Club focuses on filling the gaps for these students- we operate a discrete food pantry, load emergency laundry cards for our families, provide scholarships for science camps for kids who otherwise wouldn't be able to attend and more recently starting funding and bringing in arts to the school and funding specialized educators (garden educator, marine biology lab educator, free of charge musical theatre productions). We are entirely a volunteer based organization and need help navigating grants so we don't have to solicit donations from our school families so much but can keep making a meaningful difference for these kiddos. A strategy, introduction to tooling, actual grant writing and submitting, etc.
