Agency copywriter needed for content writing for LinkedIn

I am looking for a skilled copywriter with a creative agency background (in branding and marketing) to write a series of regular monthly content for LinkedIn. These are very short captions - on average 53 words (295 characters each). Tasks will include research and writing of short posts 2 x weekly for a total of 8 posts to be written in advance. Must have experience in branding and marketing specifically and have a good knowledge of how to write for a Linkedin audience, must be a native English speaker (sorry no exceptions) and be self-motivated, positive, deliver on-time and be flexible to communicate on WhatsApp. If you wish to apply, kindly submit examples of your content work. Thank you!
