Lyn's response was neutral and sound.

If there is no easy way to find a company to fulfill your orders, have you tried having a polite, non-emotion driven talk with your brother?

discuss his work ethic (if lacking) and what his pay expectations are. That will at least keep you covered until you find an alternative. I assume you are paying him the legal minimum requirement plus any other required benefits? If you are not sure about that, it might be easier to try to keep him happier in the job than to find someone else.

The company that gave you prices, if you were happy enough with that, try giving them another call.

good luck.
