I think Rachelle Gardner has some excellent resources on her site for writers. She really knows her stuff. I would recommend writers spend some time on her site, especially new writers. Before you consider publication it is important to know what to do in order to be prepared. Hope this helps.
Congratulations on your decision to pursue publication. As a literary agent, I’m not able to help you until you’ve created the appropriate materials:

→ If you’re writing fiction, your manuscript must be complete, edited and polished; you also need a one-sentence hook and a one-paragraph pitch. Click here to read this informative article.
