I don't know of any reloading classes that anyone offers. I would highly suggest finding someone in your neighborhood who reloads a lot and spend a few hours with them in their shop. There is much more to this hobby than just setting up equipment and making bullets to save money. Some mistakes can be fatal. Just find someone local who can show you the ropes so you can avoid making some potentially dangerous or expensive mistakes.
Just a couple suggestions to get you started:
If you shoot a bunch already, consider the Dillon 550B. You may be enticed to buy a less expensive single stage but serious shooters/reloaders always end up with a quality multistage.
Buy Carbide dies for all your rifle loads. They may cost 2-3 times as much but save you a whole lot of .
Before I started reloading my figures showed that I would recoup my initial investment after 3,000 rounds of .45 ACP. Although I am way past that now, I have learned that reloading does not save money; it just allows you to shoot more.
