Ongoing Virtual Assistant needed for business development

I'm looking for someone to work with me for around 20-30 hours per week, ideally.

I have a startup for which i'm trying to gain more clients - so mostly lead generation, business development, etc. I need an assistant to work remotely and help me.

I'm looking for someone who is keen to learn (you will learn quite a lot) and has an ability to pick up new skills fairly quickly.

Good English is a must.
Familiarity with modern apps/software is a must (e.g. any web app, Microsoft office, etc).
