Setup Followinglike for FB group posting

i have about 10 FB accounts,500 groups that i need to join and on a daily basis 10 posts that need to be posted to 250 groups daily. Everything will be private proxied
I own followinglike but really havent used it before.
I need someone to setup followinglike for me so that on a daily basis following like will DRIP post to:

DAY 1
post 1 gets shared to group 1-25 using FB acct 1
post 2 gets shared to group 26-50 using FB acct 2
...
DAY 2-10
post 2 gets shared to group 1-25 using fb acct 1
post 1 gets shared to group 26-50 using fb acct 2

its follows this same pattern,
the goal is that at least 250 posts get posted daily
