Hi Brianna,
What board district are you in? I know many school boards and regions have additional grants. You might have already found something, but I know some community clubs (e.g. optimist groups) sometimes fund school projects as well.
How has your search been going?
and if you don't mind me asking, what is the sign for? That might affect who will give you a grant. If it's for outside you school, it falls more under board jurisdiction, but if its for sports or a club, you might be able to get some support from local groups.
