What is the best way, or how would I even go about finding a Buddhist teacher or spiritual guide? Thanks.
If you have an interest in learning the Burmese system of Insight or Vipassana Meditation, which was popularized the world over by the Burmese Monk, Venerable Mahasi Sayadaw, recommend his magnum opus "Manual of Insight," (pdf) which was translated into English by the Vipassana Metta Foundation of USA. Also recommend the utube video >Phra Noa Yuttadhammo - How to Meditate< as a visual supplement, for a novice to get to grips with the subject. Incidentally, Ven. Yuttadhammo is a registered User of the Buddhism Stack Exchange.
My suggestion to you is to familiarise yourself with Tipitaka and other Buddhist books first. Then familiarise yourself with the popular teachers available at the moment by browsing internet and Buddhist forums such as Stack Exchange, Dhamma Wheel and Sutta Central. There are many not so famous teachers. But when the student ready the teacher will appear!
