Budget will be different at every facility. It is determined per patient day usually. Ask your Administrator to explain the amount you are allocated per month. Here are some ways you can event plan with help from outside sources:
1. Recruit volunteers from Universities. Maybe they will fund raise for you. They may provide hand painted decorations, balloons, offer their services for parties.
2. If it is a large community event such as an Easter Egg Hunt, or Trick or Treat. Write a letter on Company Letter Head and visit local merchants to participate in the event, donate prizes, or money.
3. Have a fundraiser to support the event. Make signs early stating the event, time, and the kind of donations you are looking for. Family members often will want to get involved and donate.
4. Start early to increase your funds well ahead of time.
5. If your units are broken up into neighborhoods the staff and residents of the neighborhood could offer to sign up and help. They will bring in items for a party, napkins, balloons, or could make something together as a group project.
Often there are many workers in the building outside your department who would donate time, talent, money, or stuff. Create personal relationships with the staff and families so you know where the hidden talents are. Keep everyone informed of your ideas and upcoming events so they have time to plan. Ask for their suggestions so they can take some ownership in the event.
Good luck with your budgeting. It is never easy, but soon you'll know what you have to do to keep things moving.
