I have been managing my own social media marketing for over 6 years and for various companies, conducted social media consultation for interested clients, and when deeply engaged can sell 5 pieces of artwork priced from 200-700 a month. This may not seem like a lot of product moved, but in my peak I was able to get 2k worth of revenue from just a few sales.
That being said; we would need to go over strategy and what platforms you want to target. Facebook Ads, GoogleAdwords, Twitter Ads, and even tumblr advertisement may be necessary. I have tools of the trade that are also 100% free and will gain marketing exposure, likes, retweets, and followers.
Please message me if interested. Some products do better on pinterest, others on twitter, others on youtube.
I will make graphics for this campaign and post appropriately and accordingly and use social listening to gain insight on engagements and ROI, regardless of the project scope. I manage my own brand, have managed over 6 companies, and within the first few days of managing a twitter account for the Moving For Good platform (@movingforgood) we've gained 600 or so followers. I am no longer managing that profile, but even my own profile, without boosting, has roughly 3.5k followers. On all social networks combined I have 20k total.
Leveraging that kindof reach can garner excellent results.
