Look around, join some Blog Hops in your genre. Join some groups on FB. Do you have a blog where you can put links to your writing and whatever? Once you get on Amazon, set yourself up an Author Central Page. And you might try joining Goodreads, aiming for short story groups and whatever matches your genre.
Being on Twitter might be a good idea too. You don't really have to spend that long on there just talking to everyone, you can use something like Bufferapp to prepare some tweets in advance.
Hope that helps some
If you add me on Twitter, let me know when you've got your book ready. I have no problem linking stuff, though I might add the caveat that I haven't read anything by your if it's not in my genre.
