Im thinking LinkedIn cold outreach would be your safe and easy bet. Start with a niche, say crowdfunding agencies or retail management agencies. These are examples from my world, and founders i know they all hire social media managers to create blog posts for them, do ghost linkedin writing etc. Then there are also big industry events like Retail Innovation Conference in Chicago, where many agencies exhibit, so you could find many of them in one place. Hope this helps. Good luck!
