John is a carpenter and has not been working for 12 months as he hurt his back and had to work at a slow pace, so he did not reinjure his back.

John's brother Peter has been doing some renovations on his home and agreed with John that he could do the carpentry work at $1200 per week for 26 weeks working at his own pace.
