What are some of the things you'd be looking for in a website describing an eco-consultant's service?

My partner’s business is tailored to people wanting to live a more environmentally friendly life and he’d go to their homes and evaluate their lifestyle and households in order to suggest changes…we’re in the process of making the website for his services…what are some of the things (feel free to write word for word) you’d want to see on the front page, so that it’d grab your attention…is it about saving money, helping the environment, helping the future, etc.? thanks, this is greatly appreciated
