Green Energy Mechanical Systems

I am a Mechanical contractor looking to become a factory rep. for wind & solar products. I wish to design, sell, & install these types of systems. I currently do plumbing, heating, process piping, cooling, geothermal heat & cool. Due to the green movement I am tring to expand on the solar and wind side. I hope to incorperate wind & solar power into my geothermal designs. The end result for my customers will be free heating, cooling, hot water, & electrial. The only cost to them will be the up front cost of the system.
