Background in design, websites, creative thinking, project management, client management, sales, marketing, social media management all apply.
But really, it's wide open. :)
Ideally you will have some background in the areas mentioned above, but PASSION and ENERGY is an absolute MUST.
If you've got design experience, send along some examples. If you've got business systems experience, showcase that. If you've got amazing ideas for social media, share them. This can be as wide open and diverse as it needs to be in order to find the right person for the team.
Share something real about yourself. Show some pizazz and energy and let's have a virtual coffee!
