How can I increase the chances that a client will choose me?

First, avoid providing services that you don't specialize in. Most clients make a choice between the wizards whose page is filled out properly. Your photo is the very first impression, choose a photo where there are no other people, your face is clearly visible. Your assessment and feedback from other customers is very important.

Write a short autobiography about yourself, something that the client is interested in knowing. Add previously completed works or specific services that you are willing to provide. This is the minimum information that should be available about you.
