With advertising, you are trying to reach your customers or clients by promoting services etc. There are various techniques you may use. But there are alot of things you have to consider, i.e. your locality, competition, profit, where to advertise, and most importantly who and what will they benefit from your product.
But i must say, that it requires alot of hardwork to advertise, usually for small business owners, its word of mouth and building strong clientelle relationship and strong connection between them because merchants alone can spread the word. Try posting on craigslist, you know how they are. And try contacting marketing managers for companies, represent yourself in a very good and strong approach. Hope this helps. Take care..
If i find a better answer il let you know, but for now, this is all i can think of.
