Why not make money as a party host? Promote yourself as a party helper and offer to help set up, face paint, cut the cake or just oversee children on the bouncy during the party. Put out flyers in your community. Let friends and neighbors know too.
Are you good with a camera? It’s helpful to have someone else taking photographs without having to pay a professional photographer. Try to get hired for all types of events. Set up a free website or make a free profile on Flicker to showcase your work.
