If you're thinking about submitting your work in any capacity, I would definitely recommend signing up for Duotrope and Submittable. Yes, both.
You get year round submission opportunities and from a variety of places. Not every publisher is a winner, of course, and if you're curious about how much it costs to submit your work, you get a more realistic understanding. This also encourages you to save to make one or two paid submissions a year.
By using them, you'll also be able to track your submissions, your rejections and acceptions, and build a small portfolio for yourself.
The difference between the two is that Duotrope has a free trial, and then it's $5/month afterward. Submittable has a free plan with paid options that offer more variety depending on your needs.
There are other submission trackers and writer communities out there as well, but as far as the two most known, most used, and easily accessible, I recommend these.
