Create and publish Instagram posts + stories for startup

I need an experienced social media marketer to manage the Instagram account for a new product I'm building. You will be responsible for creating new posts and stories that will be scheduled using Later.com / Buffer

Here is the current Instagram account: https://instagram.com/musicmagicio

Each day the account should have 10 new Stories and 5 new Posts. These can each follow the same template, but should also include the relevant location and user account tags to help grow our following. You can schedule most of the content 1 week in advance, so this task would just require your time once per week to create + schedule.

The product the account is promoting is called MusicMagic.io - it auto-generates Spotify playlists based on the music featured in the Stories and Posts of specific Instagram accounts.

You can see some examples playlists here: https://musicmagic.io/playlist-categories/

Please provide your cost 'per week' for managing this account based on the above requirements.
