Don't hold me to this, but I think it's around $17 per hour. I think you also get raises every 6 months for your first two years and another raise if you can get promoted to tech II. That's how it was several years ago, maybe someone with more recent information can chime in.
Keep in mind the job is potentially dead-end as there is nowhere to advance to unless you want to go into management. Also TSG has been downsizing nationwide over the past few years.
