Finding your first client is always an hard mission. You need to be creative and sometimes think out of the box. Mainly your first clients will come to you from mouth to ear and they will probably be friends or friends of friends. My advice is to ask for low price then the market at the beginning, it will gain those clients that will want to earn your low price. Give the best service you can and they will pass your name to their friends. That way in no time you will be able to collect some happy clients and build your portfolio. Good Luck!
