Outstanding post, @susanne! In addition to providing great details as to how to get started, this is great insight into your work-life!
My youngest daughter was essentially doing this exact thing for a media company here in the states. She worked remotely and handled everything from content creation to social media engagement. She did a fantastic job, too!
Have you read "The Four Hour Work Week" by Tim Ferriss?? If not, you really should consider it. That book would speak loudly to what you're doing and how you are working remotely...
Cheers!!
