renting quality facebook group

it's french group , i was posting there for free until the admin decided to take action, so he has facebook group with 60k members, i have a good experience with french traffic since their CPC is generally fine, he will charge me 60 euros a month and i'll be able to post 5 posts a week, i never rented a facebook group before, so what are the prices in general ? is it worth ? 60 euros for facebook group only 20 posts a month.

I'm paying a rent of a facebook page 89k + group 8k for about $15 bucks a month. locally. CPC $1.5-$2
