Looking for advice and theme choice for a charity website

Hey everyone ??

I’m looking for some pointers on what theme would be a good choice for a charity website to help a sick child raise funds for a life saving operation, it needs to be clean and support a donation link with a tracker if possible, also social media buttons included.

Also does anyone know of any plugins that can be used to take donations ?
and of course any must have plugins ?

Thank you everyone in advance who can give some pointers and advice.

Regards,
Richie
