I would note there is a distinction between club/ISWA & academy/ISWA routes. Clubs are good for beginners and those wanting to get their son or daughters feet wet. Most clubs are seasonal, often running between October to May at the latest (assuming they wrestle the ISWA freestyle season). That said, the top high schools may have feeder programs going on year round (more like academies). They are the most cost effective and depending on the coach and club very good. Good clubs will produce very good wrestlers.
Academies run year round 3 to 4 days a week and cost around $80-$100/month. That doesn't mean athletes have to go year round, only that they are available. Some wrestlers take few months off or reduce the number of days they attend during baseball &/or football seasons. Wrestlers in those rooms range from beginner to High State champion. The rooms are focused and serious, but that isn't to say they aren't fun. There are lots of little guys just starting. If you decide that route and given your distance parameters, I would second julia2009's recommendation on CIA. They produce top notch wrestlers at all levels.
At every step from starting through High School you can see the distinction between beginner, elementary club/ISWA, starting at middle school & academy/ISWA before they ever step on the mat.
