Please note that I am not an engineering consultant. I write and lecture on the subject of wind energy and increasingly on other sources of renewable energy as well. I do provide advice to governmental, non-governmental, and advocacy organizations. I can provide referrals to technical consultants upon request, some that I recommend are listed below. Note also that as a free-lance writer I do not sign non-disclosure agreements. While I respect confidentiality, I am under no obligation to do so.
There are dozens of firms worldwide providing professional services to the wind energy industry. There also a number of planning bureaus in Germany that specialize in siting medium-size wind turbines throughout Europe.
For an interesting and well written commentary on what it's like to own a 1.8 MW wind turbine visit Glen Estill's wind blog.
The following are meteorological consultants that I have worked with or who have helped me to understand wind resource assessment. They are professionals and because of the boom & bust nature of the wind market in North American can be extremely busy. They can't take the time to answer general inquiries. They do provide wind resource assessments that will withstand the scrutiny of a banker. Wind studies cost from $25,000 USD to $40,000 USD or $25,000 CAD to $50,000 CAD, depending upon the amount of work required.

Remember that trade associations are in business to promote their member's products. You won't find information about the German manufacturer Enercon on the web site of the Danish Wind Turbine Manufacturers Association. Many of the European web sites are offered in English as well as the host language. Some, such as Vindmølleindustrien's extensive web site, are presented in English, German, French, Spanish, and Danish.

There are two organizations in North America that are actively encouraging community-owned or farmer-owned wind development: Windustry in Minnesota, and the Ontario Sustainable Energy Association in Canada.
There are also a number of organizations and environmental groups that support wind energy.
Ontario Sustainable Energy Association
Pro Wind Alliance
yesPro Wind Alliance--A voice of reason in the British Isles not connected to any trade association.
World Future Council
World Future Council supports the use of Advanced Renewable Tariffs (feed-in tariffs) to encourage the rapid development of renewable energy. Community ownership of renewables is only possible where effective feed-in tariffs are in use.
The Folkecenter for Renewable Energy is a long-standing reference source on the success of Electricity Feed Laws and Community Wind development in Europe. The Midwestern Renewable Energy Association has long been an ardent proponent of renewables, not just wind energy.

For an insightful account of the history of the Danish wind turbine industry and the role they played in the development of modern wind energy see Erik Grove-Nielsen's web site at Winds of Change. The site contains one of the best collections of photographs from the period as well as a hard-to-find collection of historical photographs. For more information, see the History of Wind Power.
Mick Sagrillo also organizes the annual Small Wind Conference in mid-June at Stevens Point, Wisconsin. Mick bills this event as a gathering of installers, manufacturers, dealers, distributors, educators, and advocates. It's the only event of its kind in North America.
If you need parts, service, or advice on how to maintain your small wind turbine, you can subscribe to the yahoogroup small-wind-home. Don't let the broadened term Home Energy Systems deter you.There are several knowledgeable participants on this list who offer a wealth of technical information. Once you've subscribed, monitor the list, then, when you're ready, post your question.
There is also a discussion group in French on small wind turbines: petit éolien.
