Hi Chris.
I have a couple of suggestions for you to consider RE: Your advertising/marketing plans in 2012.
After having a brief look and your website and services, I think you have some significant opportunity to create some very good results oriented cold call campaigns.
Take just one of your services like Motorcycle decals/stickers as an example. Rather than just have the service listed as a small component of your larger operation. I suggest you create a flyer specifically showcasing what you can do with this service, add a good value deal and then cold call every club listed on the Motorcycling Victoria website. - 65 motorcycling clubs with contact details right here >>>>

If successful, you could then do the same with Boat Racing clubs. To take a step further than that, you could even go directly to Motorcycle or Boat shops. Speak to the owners, set up a deal with them that includes your service in their purchases prices (just give them a fiscal incentive to sell you!).
Although I agree with all the previous posts about pumping your Facebook and paying for
SEO etc. I am of the opinion that they're the kinds of advertising initiatives you focus on once you have developed revenue streams and want to step it up a notch. My above suggestions are more practical, inexpensive (just labour + some printing) and are very results orientated where you can easily measure your success/failure.
Hope this helps.
