I could see someone offering a newbie systems programmer 100 bucks for a pronto program, but crestron is another story. If this friend of yours is selling crestron control systems, then he is literally screwing you if he expects you to program touch panels for a mere 100 bucks. As a company owner, I sub contract crestron programming for 75-100 bucks per hour. Some systems take 5 hours, some take 30.
