How to get more orders as a music transcriber?

I work as a freelance music transcriber via the internet. To generate orders, I copy and paste the same advert on various musician related discussion forums, as well as in the 'musician services' section of Backpage.com

Over the past few years I've managed to make a reasonably steady extra income doing this, so that tells me there is demand for this service. However, I have to constantly paste the ads out there, otherwise the orders stop coming in, and it takes a lot of time to keep posting ads everywhere.

But I'm wondering, is there a smarter and more efficient way to generate enquires from people who need a piece of music transcribed?

I don't have a website, but I'm looking at a way that when people search Google for 'music transcribers' or 'music transcription' that they find me and they can then contact me, so I can generate enquires on autopilot without having to sit around pasting ads all day.

How do I do this? Should I set up a site with sitesell.com, which helps generate a lot of traffic and income? I have heard that sitesell is an idiot proof way to set a website that people will be able to find on Google.
