Once you're through with the proofreading/editing stage, you're probably ready to look for a place to send your story--assuming, of course, you don't already have a market in mind. There is a great website out there that offers current listings for a variety of print magazines, online zines, and upcoming anthologies. The site is http://duotrope.com/.
Once you go there, you can use the pulldown menu bars on the left to search a variety of genres and subgenres, then break it down further to look into such specifics as medium (print or electronic), payscale (none, token, semi-pro, and pro), etc. I've always had more luck searching under markets that offer token payments ($5 to $10 per story, regardless of length), but I would advise that you explore the options yourself.
When you read up on a particular market, please make sure you read their guidelines carefully...that's the next big topic we'll tackle here. Philippians 4:13.--SMS
