I don't know of any workshops, but you might want to try Scott Kelby's World wide Photowalk. I met quite a few folks a couple years ago when I moved to Philly that I stay in contact with and attend other events. There is one in Greenville, too.
Forrest Briggs Photography Hands on workshops are highly recommended. If you are still interested Eduard, I attended one recently and it was arguably the best photo classes I have ever been to. Forrest has a gift for simplifying photography. He is friendly, knowledgeable, and his class improved my photo skills tremendously. Great class!
