I need social media management of Instagram and Facebook accounts

I need someone who is competent in sourcing interesting and RELEVANT content for my social media accounts. My business is an on demand beauty application targeting afro hair, alternative beauty and women of colour so the content of the posts MUST reflect the demographic. I would require someone who is apt in the relevant hashtags and titling of the posts with 3 posts a week minimum required on Instagram and facebook to help raise my following and grow my social follower engagement. Need to begin with immediate effect for a beginning trial period of 2 weeks.
