Shalom,   It takes a lifetime, many resources are available both  online and offline. 1-If you want to learn say the Zohar in English and Hebrew you have the wonderful Zoharinenglish.com project that has bereshit and Noach available now for free.   2-If you want to learn the arizals  shaar ha pasukim or mitzvot there is a superb book called Apples from the Orchard that has both Hebrew and English with full commentary.  That’s over 2000 pages of in depth study just to get you started between the free Zohar and this book.  It might be available at the library or an online shop.  Even at $100 it’s completely worth it since it can be reread as a reference for many years.   Online teachers that guide Kabbalah study are expensive since tutors with that much training knowledge will generally only accept very selfless dedicated students that are willing to make the study a major priority.   If you wish after you have familiarized yourself with the 2 books I mentioned above and have a decent working knowledge of them , I can recommend some further assistance with some of the tutors I know.   best wishes—- R.
