Ask HN: Quickest way to create a Covid-19 volunteer job board?

I would like to create a job board for people to post COVID-19 volunteer projects.

I am of the belief that the coronavirus spread is a dangerously multiplicative process and slowing its spread now is critical. The merits of this belief are not what I intend to discuss here.

Like some popular freelancing sites, it would include profiles for willing volunteers as well as posts for projects that are needed.

Are there any freelance site themes available on common platforms such as Wordpress? Do you have any better ideas for paths to explore in order to build such a project?

Thanks.
