Rick's class is usually one-on-one, so the procedure is to call him and set up a date when you're both available. You could ask him what his prices are before you commit to a class. If you and a friend or relative wanted to take his class together, I'm sure he could arrange that too, and you should get a price from him for having more than one person in the class. Rick also does group classes from time to time, and you could ask him if he's scheduled any that are close to where you live.
Rod Jenkins is an (or maybe the) owner of SafariTuff, which has an ad at the top of the Shooters Forum. If you emailed him through SafariTuff, maybe he could provide you with a list of classes he has scheduled. Whenever he schedules a class, it is usually posted by someone on TradGang, because they are usually looking for a few more people to fill out the class.
