Comment Spam Conversion?

I run a local business and am looking to generate leads by comment spamming at the bottom of news articles of my city & local papers. I will include a link that directs to my "3rd party lead generating site", not my company's site. I realize my accounts will be suspended, probably on the daily, but I can just setup a new account w/i 1 minute and be at it again, bombing article comments with my ad. Each contract, or sale, I earn will bring me roughly 3.5k a year in revenue.... is this worth it? Do you guys have any ideas as to the conversion of this type of spam?
