I responded to an ad looking for someone to write a 300 word article for $15.
Me: Hi! I’m interested in writing the article you advertised for. Can you send further information regarding the job?
Client: Hi! Glad to hear from you! We pay $30 for 1000 words and $15 for 500 respectively. The main topic is online gambling. Are you OK with this all?
Me: 500 words for $15 is a bit low, but I could do 300 words for $15, as specified in your ad.
Client: Sorry, but our pricing is fixed.
