Sometimes, its wise to start this way, aside from giving you more experience, you also gain a lot of people's trust. As time goes by, you may decide to increase your fare, and people would still patronise you, that is because you have worked for them at a cheaper rate, they have seen the quality of your work and they trust you enough to handle bigger jobs. I wouldn't really advise anyone to start expensive though, and I won't advise anyone to hold on to cheaper rates for too long. It is just a phase, you get to move forward and grow bigger along the line.

Nice post by the way.
