My back-catalogue of workshops I have delivered working with Kepler College - mostly two-hour illustrated lectures followed by discussion - are now collected in one easy spot right over here.
These include Geomancy for Astrologers - which, despite the title, provides a firm 101 foundation for anyone looking at geomancy and is certainly not merely for astrologers! - as well as my Fundamentals of Astrological Magic series (for which you can find a review of that here and testimonial from it here), and my recent Planetary Incantation series, which can be bought as a discounted 7-part whole or as individual workshops.
