Virtual assistant with experience in social media marketing and MS Powerpoint presentations

Hi there,
I am looking for a part time VA to help me run the admin side of my two small business. Both are in the Natural Health industry.
I am looking for someone who is proficient at SEO and social media marketing (Instagram and facebook), and is comfortable putting together professional Powerpoint presentations. Knowledge of Movie Maker or iMovie is also helpful as I will require some video editing down the track also.

Basically I am looking for someone who can help me put some content together for my businesses and then get it out to the rest of the world.
I will give the right candidate a Powerpoint presentation to put together for me over the two weeks. If I am happy with this work I will then employ you long term to help me with my businesses.
