Hi there, The Writing Barn also does a good job with teaching. They have a lot to choose from, some things are one-time webinars, other things are longer term, community-support based classes. thewritingbarn.com
I have been to many Highlights workshops and classes (more when I lived on the east coast and pre-publication) ovr the years, some for a week, others for a weekend, and they are always excellent.
There is always the option, also, of hiring a writing coach who is with you the whole way.
But what you are doing is exactly how you make it happen, you are asking questions, you joined SCBWI, and you are seeking help. Good for you!
