Sounds good,
@Sea-shore.
Yes, there are writing workshops and some are more affordable than others, most offer free places to those from poorer communities and translators are around to help people who write in vernacular languages. Some workshops are run by international 'experts' and cost a fortune. I've only done one or two workshops years ago and haven't found them especially useful. The atmosphere of a workshop can be quite distracting if you need to sit and write, and suggestions are quite prescriptive and one-size-fits-all. The feedback is variable and for many writers, making new friends, socialising and finding beta readers is why they go along.
I've participated in a few free online writing courses: How Writers Write is a successful MOOC based at University of Iowa. They use videos made by teaching staff and writers-in-residence and have instructors moderating the discussions. The focus is primarily literary, although one or two groups look at sci-fi/fantasy. There are set writing exercises or pieces each week. Some participants try to post excerpts from works-in-progress but often these don't 'fit' the exercises. All the basics of strong openers, POV and voice, dialogue, uses of conflict, characterisation, building narrative arcs etc are covered. The forums for discussion are well-moderated and generally supportive, but MOOCs have large numbers and many posters for whom English is not their first language, as well as beginners, published writers and MFA graduates all side by side. An interesting mix. Like most academic writing environments, there isn't much focus on the nitty-gritty of what it takes to get published. And no sustained community -- you all meet and exchange ideas, share work, and a few weeks later, it's all over until next year! People can buy video packages after the course, I don't know how many do that.
