Advice on Grants and Funding for Trip to Africa

We need advice and guidance on how to find grants, organizations, and/or companies that would donate to a nonprofit like ours.

This foundation has been to Rwanda Africa 2 years in a row with 8 people on the team each time. The trip costs $3,500 per person, including the plane tickets. We hope to earn grants through a variety of different areas, but are unsure of how to start.

We have seen donations from the community come to $1,000 each year. We have built a GoFundMe page, but have not found success in that.

This upcoming year, we hope to gain $30,000 in grants to pay the way for volunteers to come to Africa. Many of the volunteers who come are college students who cannot afford to do it year after year. We also hope to use these grants to allow for more volunteers to come.
