Digital Marketer for ongoing project

We are an Australian based startup looking for a digital marketing freelancer to help us scale our paid marketing efforts to our global customer base. Our product is a mobile shooting simulation system (Virtual-Shot) that creates some challenges for paid social marketing due to the nature of the product. Our ideal candidate would be someone that has experience with firearm related products, but this is not a must. Ideally we would be looking to work with a freelancer on an ongoing basis over the next 12 months and looking for a weekly commitment of between 4-8 hours.
