I am not sure if there is such course. However, if you are really willing to learn the hobby either by taking a course or learning from a friend or someone who is willing to teach you how to reload, you will still need to do some reading first to know the process. Either way you will have to do your own homework by doing a lot of reading before asking someone to help you. The best way to start is buy a reloading book. Lyman 48th Edition Reloading Handbook Manual is a very informative handloading book for begginers. Read everything from the start, it will teach you all about the history, do's and donts of the hobby. The first part of the book is intended to educate new handloaders about the hobby.
DO NOT jump into the reloading pages right away unless you have read the first chapters of the book prior to the reloading data.
By the time you are finish reading the whole book, you will be in a good position to figure out the equipment you will need to buy. You will have sensible knowledge on how to reload and you will have sensible questions/clarifications to ask whoever is willing to teach you about reloading.
IMHO, the key to success in safe reloading for begginers is being well informed by doing a lot of reading first..... READ, READ, READ, READ, READ (have I stressed it enough??)

Follow the guidelines and the "Divine Rules" when reloading.
Good luck and reload safely
