Digital marketing for Instagram & Facebook, Meta business

I am currently using Facebook and Instagram marketing. But it is not working perfectly.
I need a digital marketing specialist to improve and upgrade these marketing tools and connect Instagram and Facebook businesses together in order for me to use them conveniently.

I boosted posts via instagarm but i could not see the boosted posts from instagram
Also i want to connect instgram to facebook well. I tried to do that myself. But it seems not perfect.
