Virtual Assistant

I am looking for a virtual assistant to help run my production company based in the USA and the Caribbean. I need help with sending and responding to emails,
calling agencies and scheduling meetings,
following up on clients,
looking for new clients,
setting up new online accounts
travel arrangements
social media
hiring and outsourcing
etc.
I am looking for someone that has a deep understanding of digital content trends, fashion and travel media. The aim of hiring a VA is to attract high paying clients and improve my quality of work

thank you.
