The best way to land a client, and the only way I've found so far, is to implore those who love you to give you a chance. Family members, friends, friends of your family. Start with anyone who has a positive opinion of or an emotional attachment to you. If they want what's best for you, and you can convince them that hiring you is what's best, they'll be more inclined to give you a chance. I started by offering to do some work for free, although everyone says not to do this.
