I will be able to your product by reaching out to maximum prospective buyers through various social networks available these days. However, it will really depend on what kind of product you are trying to sell. I have the experience doing such sells in the past and have been doing, so I think I can do it for you as well.
You product could also be sold by advertising in google sites through their marketing schemes such as adsense, adwords etc. If I'm found fits to sell your product, do let me know so that the project can be started immediately.
