Social Media Marketing Manager

Hi. We are a software company. We have developed a B2B App which works on Android, iOS, MacOS and Windows platforms. I am looking for a Marketing person who can create one graphic along with writeup and hashtags and send to me every day. I will post it on all my social media platforms. All three elements "Graphic", "Writeup about that Graphic", and "Hashtags" are extremely important. So only the candidates with detailed marketing knowledge may apply. This will be a very long term project and if your performance is good, then I can offer a few more accounts.
