There are two sides to a coin.
People who are interpreters decide to provide their services at a lower cost as part of a contracting process. They're members of your congregation, if I can call it that. However, they choose to provide their services at a lower cost as part of a process that's currently delayed but that could be implemented. These people are, if I may say so, on your side of the fence, and they can choose whether or not to provide their services at a lower cost.
Why do some of your members or certain people who provide the same type of services as you want to do this?
You'll probably mention the fact that these people want to earn a living. However, if everyone wants equal services of equal quality, why are some of you willing to provide the services at a lower cost?
