Hi there, sounds like a cool business.
If you're looking for a place to post your adverts for free, check out:
I've recently been posting some image ads I've created myself, as well as images of business videos I've made, and hyperlinked them to my site so the reader can watch the video.
Both of these have been working well, and I'm getting calls from interested potential customers. Perhaps this might work for you too? Fingers' crossed :-)
Another technique which I love because it's free, it's easy-to-do, boosts traffic to your website, gives you credibility online as someone who knows their stuff, is VIDEO MARKETING.
You don't need to be a clever video maker of any description - you just have a smart phone (iPhone, Blackberry etc,) or digital or video camera to be able to make one-minute videos answering any QUESTION someone in Ontario might type to find a service like yours.
I've used this successfull for myself and clients and love it!
In fact, I've just posted a page on my site with all the tips I recommend to all my clients for this technique - and which works in all industries, so you might find it interesting enough to give it a shot too.
It's a step-by-step process you can follow, and once you set this up (answer at least ten top questions people might ask you), you'll be boosting your website traffic incredibly.
Because you're targetting local businesses, remember to use the "location" keywords in your on-site SEO, your VIDEO SEO and video transcripts, e.g. ontario, canada, and any other relevant towns or districts.
Best of luck! I'd love to know if any of this is helpful, and I wish you much success with your business.
Personal experience, recommendation to clients who've had much success with my "video questions" technique
