You could start in your local paper. I Live On Long Island,New York and we have the Penny Saver or Newday. Pennysaver is about $15 for 2 to 3 areas. Area meaning towns on Long Island. Each Town may have 25,000 people. So if you place your ad in let say 2 towns that about 40,000 people give or take. You will reach those people you want to sell to. Maybe 5% will be interested. That's about 2000 people. At 2% is about 800 people. 1% about 400 people. 1/2 % 200 people.
So lets say you sold 200 people and Item at $47 a month that would be about $9,400 a month if its residual income. What do you do with that money. Simple reinvest lets say 20% into advertising. Which is $1880. You say that's to much but watch. Now let say you are reaching 10 million people. You get 1/2% of that actually buying. Lets say a 1000 people. Give or Take. You sell a product for $47 at 1000 people that is $47,000 a month residual income. So what do you think about the possibilities. Start small. I have been in business for 25 years. I ran a Landscaping business and a Cleaning Company. I advertise plus word of mouth and we made plenty of money. Internet not much different. Again Start a small advertisement that is catchy and chaching the money will start rolling in.
I hope this helps. Don't be afraid to take a chance. Write something you think your audience is interested in. Make it catchy and interesting. Good Luck.

Ah well now you've put it like that... makes a lot more sense. Will have to go back and take another look now. Thanks for the explanation
