Crowdfunding for restaurant through/ future meal vouchers

Hi
I am chef - I own www.andaazrestaurant.com
We had to close operations due to lockdown - and don't know when we can re-open
The Government here ain't doping much - no grants, no special loans
This restaurant is located in the red light district - we have rehabilitated hundreds of ex-sex workers, and have been providing culinary training employment to troubled youth and transgenders.
We are proud to say we are/were the best Pakistani restaurant here - and one of the top one, in the world
My people work on monthly wages - to let them off in these dark times will be detrimental to their well being
So I want to design a campaign targeting our patrons and public at large - to support us by buying futurre dinner vouchers - a digital platfform is also being set up for this.
