In-person workshops to learn marketing design?

Confession time: I feel like I completely suck at marketing + design, which really impairs my ability to create good, compelling, professional landing pages. And that's a problem since marketing falls under my responsibilities as the non-technical cofounder...

I know there are tons of landing page builders out there -- but it isn't much good if you don't have the copywriting chops to figure out what to say.

Does anyone happen to know where I can find marketing/design workshops? I'm already planning to attend MicroConf next year, but I gather that's more high-level. Looking for something hands on and in person where I can learn copywriting, Sketch, etc. I've done a ton of reading online but really learn best when I have the chance to interact/ask questions.
