Hello my name si Laura , i'm from Argentina.

I'm new to the city, I want to publish as a freelance, but I'm not sure where to do it.
can you help me?
Since the agencies offer me only £ 50 an hour.
my email is lauritaxxx506@gmail.com

¡Bienvenidas! You didn't mention what city you are in, but here are some good resources for advertising (publishing):

You won't find much support on this forum for working with agencies. They tend to exploit women's time, work, and money for their own profit.  You may not want to publish your email address here as well.
