I started about a month ago and created my first thread to offer skilling services in the same day that I made my account. I didn't get any customers straight away despite offering lower rates than other users. I don't have a lot of experience in the market, but from what I have seen people are prepared to pay more to receive a service from a highly vouched user rather than go to a newcomer.
I feel I was lucky in the fact that I provided my first service I think 3 days after starting. I think the wait for the first customer could easily have been a few weeks/months. However, since then I have slowly been able to provide more services and even have a few regular customers now.
My point is that things started slow as users didn't really trust me. I got told many times that I wasn't vouched enough or simply got ignored. I know that many users will still not trust me as I have a small number of vouches, but that is not going to stop me from offering my services.
Being patient and persistent is key, especially when you start out, but if you keep going good things will come from it. This is exactly what I plan to do and is the advice that I would give to newcomers who are serious about being active in the market.
