Being a newbie, if you really want to attract clients, I suggest that you lay down all your experiences and let them analyze and decide on it.
Finding a job nowadays is hard due to a big competition, in both online and offline world.
It's like finding a job in real life where we put all our experiences and qualifications in the resume we submit.
Sure. I can do it if client contacts me.
This is a non-professional attitude and i am afraid if you can't get any work without first telling people what are you good at and your previous experiences.
Online job finding is similiar to find job in real life, so you should follow the same guidelines. Good luck .
