Hi Darragh,
I am new to freelancer website, but I have almost 5 years of experience in Online Marketing, including Social Media. I have been working full-time for a number of companies, always getting a positive feedback based on my results. I have setup from scratch marketing activities based on the best practices I've developed over the years.
I am setting up my bid quite low, not because I evaluate my work so low, but because I would like to build up my Freelancer account first by delivering high quality results, without caring about how much I earn for it at the moment.
All the Best,
Maria
