Business card with logo

Information for the business: Energy assessment for housing, green retrofit
Design details: For a startup company I need a business card incorporating a logo, company name and contact details plus potentially a headshot of myself on the back (this is optional). Some terms to sum up the business are:

Energy assessment
Domestic retrofit consultancy
CO2 reduction
Low carbon footprint
Energy saving
Content to include: logo, Green Building Design Ltd, URL, phone, email, optional photo
Ideas for the visual style: simple illustration, a few colours professional in an approachable manner, but not cute (e.g. not a scarf wrapped round a house)
Things to avoid: cutsey
Preferred colors: olive green, white, etc
Urls to draw inspiration from: https://nest.com/
Extra notes: I like the clean, simple lines in nest.com though think the images are a bit large. Anything that resembles good wordpress blog. For a hint re my design preferences/feel, here are some pins..
