If you already have the title and abstract for your article, you can use the following tools from Elsevier and Springer to help you pick a right journal among those that belong to the respective publisher
http://journalfinder.elsevier.com
http://journalsuggester.springer.com
The output of these tools shows inter alia average article processing times and impact factors of the journals, and usually also publication fees and/or open access fees. In many cases you can publish free of charge if you agree that your article is NOT open access (i.e. available only to journal subscribers), but you should check this for any given journal separately.
Once you make a short list of potentially suitable journals, you can check whether they are covered by Scopus here
