Hi there,
Having seen your project details, I wanted to get in touch - it looks right up my street.
Firstly, I am a UK citizen, currently living in Thailand (can work flexibly to your schedule) and working with clients all over the world in different time zones. For me, its about a better work/life balance and also i'm quite new to freelancer but have many years experience in the space.
On my experience, i've been working in online marketing for over 17 years, and in social media since 2006. I have created content calendars like the ones you mention before and activated them across multiple platforms and even in different languages before. So this is no problem for me, exactly the type of work i'm looking for.
I would approach this over 2 phases, one the research phase, getting to know the brands you have and the competitors so I am familiar with the type of content being activated in this niche, what works, what is success, what type of goals can be achieved etc.
The second stage is activating the content and optimising the posts so that each post has the most opportunity for success.
I look forward to hearing from you and the opportunity to work together in the future!
Many thanks,
Jason
