Selling affiliate products through classified ads??

Hey guys I wanted to ask A question and I would greatly appreciate your feedback. I am new to internet marketing and am just brain storming on ways to sell affiliate products. My question is if you think that I would be able to sell affiliate products through classified ads if the classified ads were ranked on the 1st page of google for A specific keyword? Say for example A keyword that gets somewhere in the range of 1,000-3,000 searches per month. My idea is to build an army of classified ads on different niches and get ranked on the first page for A specific keyword. I have A subscription that would allow me to place unlimited ads and each ad would autorenew itself after 30 days so that they would run on autopilot and the only maintenance I would have to do would be to add some backlinks to make sure I stay on the first page. There would be some traffic from the ad site and also traffic coming from the search engines if I am ranked on page 1 for the specific term being searched for. My affiliate links would be added to each ad and be cloaked.

This is not the only plan I have and this certainly won't be all im going to do but I thought this might be A way to create A stream of income that would basically run on autopilot other then making sure I stay on the 1st page for each term since the ads will be autorenewed and not expire. I would basically just need to add some backlinks here in there to make sure I stay on the 1st page and every ad I create would stay up and autorenew itself. Please let me know what you think of my idea and if you think that it will work?

Thanks
Erik
