  • A film night - £100
    Whether it's a retro classic or so bad it's good, get a space, some popcorn and invite people to a cosy film night. Ask them to pay what they would in a cinema.
  • Sweepstake - £100
    Who'll win the grand national? How many sweets are in the jar? Set up a sweepstake and watch the money roll in.
  • Dinner party - £150
    Wine and dine your friends and family by inviting them to your home for a dinner party. Ask them to pay what they would in a restaurant.
