Ans: Dear Anonymous,
What kind of freelance writing work are you referring to?
If it is for magazines or newspapers, you need to pitch in your idea in maybe 100-150 words.to those publications that want relationships writing. The editor-in-chief or the person responsible for choosing ideas that are submitted will contact you if there are interested in your article. You can then pursue your writing and submit the article to them.
A few publications pay per word and a few of them do not pay. So, if this is a profession that you want to get into, you might need to have a credible background to be able to write for publications. If it's an area of interest, then do a check on the internet as to who is taking in submissions.
All the best!
