I have come across a product which I use myself at home. It amazing, far better than alternatives that people generally use. The product in question isn't expensive either, though around two or three times the price of the regular compeitition. The compeititon on google is low. I am sure if I do a really good review (from my own personal experience) I can sell loads of units. Will a four-five page site work? To be fair, I think a five page site will be a stretch. Before anyone says to build a list I got to tell you this isn't a product worth builidng a list for. I think the best way to monetise is to do build a dropship relationship with supplier or affiliate with Amazon. Or to increase margins, buy in bulk, then sell on Amazon and eBay. The latter method is not an option for me (beause of storage issues). I could have perhaps done some PPC if I sold directly, but the margins thorugh affiliating will probably be too low to make it worthwhile.
