People laugh at prices because in their mind the work required is not worth price stated,
You need to sell the price you quote so the customer sees what they are getting for their money, I quoted a job on Saturday morning which was £860, the guy nearly passed out! He told me there was no way he was paying that, it wasn’t until I was leaving that I mentioned it was a 3 man job at that point his attitude changed, he thought it was just me ( it was my fault I hadn’t given him enough information to justify the price) so the price was the same but now he thought he was getting his monies worth.
To get back on topic about training, if you want to use your training in your sales presentation then tell the customer a white lie. when you inspect the suite or carpet tell them what a coincidence it is that their carpet or suite is the exact same one that was used on your last specialist stain removal course, then tell them a little bit about your ongoing training schedule to learn about the many new fabrics that are being used by modern furniture manufacturers ...bla...bla....bla...bla
