Admin to share post on Facebook

I need someone to share posts from my clients FB pages. We have 5-8 clients at the ---------- nt.
I post the ad on the page and I need you to post it in 50 - 100 groups
We post Monday to Friday but may require weekends
You can post from your own FB account ( but it will not show your name as you are posting from the company ) and we can provide extra accounts
using different account to bump it up with comment 4-5 hours afterwards
This is a simple job but requires somone to understand a few groups that should not be posted in ( i.e Industry groups )
I need someone to start ASAP, so the early bird will get the job
