I feel like the fact that you don't clarify how difficult it is to get accepted by these publications really hurts the helpfulness of this post.
Clarkesworld, for instance, is really, really hard to get into. You have to write an amazing short story and compete with thousands of other submitters just to get accepted. Your odds are like .001%. "It won't be easy" doesn't even begin to cover it. You make it sound as if you could just send a short story their way and you'll probably be published
