Our techs get paid flat $10/hour for training without commission. Once they are ready for their own (usually after a week or two of training) they start getting salary plus commission based off jobs completed. The LEAST someone would make per week would end up being $12.5/hour. Thats assuming they completed enough for the first commission. Most everyone can reach this. This is also assuming they worked 40 hours. If they completed this in less then 40 hours then since its salary they'd be making more per hour.
Our best techs are making $20+/hr weekly, many times more if they get a cake route week.
