Very small wind is a challenge. To take advantage of your wind resource, a wind turbine should really be about 9m above any obstacle within about 150m (see http://www.homepower.com/articles/wind-power/design-installation/wind-matters?v=print, for example). With a very small turbine, the cost of the tower to get a turbine up this high can dwarf the cost of the turbine itself. If turbines are installed at lower heights, they are likely to fail prematurely from turbulent air, and will usually not perform well. Often solar electric systems are more cost effective, even in areas with a marginal solar resource.

But that wasn't exactly your question. For a good rundown of a number of home-scale wind turbines, check out http://www.homepower.com/articles/wind-power/equipment-products/2014-wind-turbine-buyers-guide. These are probably bigger than you would need, but will give you a good sense of what quality equipment is in this market, and their cost.

Some other potentially useful links:
