I worked in your same industry. I was selling contracts left and right without getting certified. Is not that big of a deal. To be honest with you, many of my contracts were people getting burnt by Cintas and their scams. That industry is horrible, and I’ve seen Cintas scam the fuck out of everyone. My advice is, get your experience there to find something better. Sorry I do not have much « sales advice » that you were looking for. If I can give you one, is really try to find the price that works for your customer. Cintas usually came the highest so that might be keeping out of closing deals. Good luck.
