We have a online store selling vitamins and supplements to consumers in Singapore. We also have a digital agency in Singapore which help us with some of our Facebook campaign. We are now looking for a freelancer to provide us with additional help to provide strategic direction on the type of facebook advertisement campaign which we should launch every month, optimize our Facebook advertisement campaigns, advise us on ad set targeting, and improve our ROI on facebook marketing. The freelancer should quote us a monthly retainer fee without graphic supported needed. We will draft up all ad copy and design the advertisement.
