1. Does anyone know what the typical sales chain is for wind turbine companies/startups?

Is it typically... company->distributor->retailer->consumer

2. What would a ballpark number be on how many units are sold in years 1, 2, or 3 of a company/startup?

3. What are the ballpark gross profit margins for the average company/startup?
Is it 25-50% or does anyone know of a more specific number?

Thank you in advance!
