Connect FB and IG business accounts

I'm looking for an experienced freelancer to connect my Facebook and Instagram business accounts. I need a basic connection established which will allow me to share posts, stories, and comments between the two platforms. I currently have some existing ads and campaigns that will need to be considered during the connection process. Once connected, I won't need post management services for now, although that may change in the future. All other requirements will be discussed in further detail with the chosen freelancer.
