You can host a cocktail event either in your home or at a restaurant/bar. This is as simple as gathering a group of friends / acquaintances, throwing a party, and asking them to donate via various ways.
Some ideas for raising money at a cocktail event include:
1) Using a ticket site such as eventbrite / splashthat to sell tickets to attend the event
2) Hosting a silent auction, and gathering auction items in advance of the event
3) If you’re hosting at a restaurant or a bar, asking for the bar to donate all tips or a portion of their revenue from the night
4) Having a live auction for larger auction items
