My Target market is forum users that use the classified/for sale section of forums. How would I go about generating a buzz targetting those people? Service is similar to ebay's rating/feedback system.
Post in the forums with helpful information. That way you establish your credibility and you can link to your ad post.
Natural word of mouth start coming up once you achieve reliability and when the service & support are extendedly well, for short term WOM you should offer something to your existing clients to refer others or implement viral marketing.
