For manufacturing, you will probably have to check out the local agencies.
I am not sure about the local, but some agencies quoted around 50-90K per person for the assistance to my friend. (IT)
He gave them the option- of 50K extra pay without assistance OR the assistance. Everyone chose 50K. 😅
Some agencies don't even charge anything to the job seekers but to companies only. So, if you go to them with the requirements, they may quote some numbers.
