I need to tap into fundraisers who support veterans. I am not sure where to begin?

I am working on a grouping of events www.storytellersproject.com and I have over 30 veterans groups who want to do events. I volunteered to help them raise funds to do so. I’d like to reach into the community to find companies or individuals who support veterans & would be intersted in this project. I need a little “push” to get started as I feel a tad overwhelmed.
