Design a new logo in one hour

We are Grosvenor Interiors, providing a full service for high worth clients including, Design, Project Management and Specialist Contracting. In recent years we have undertaken a number of projects for the Teenage Cancer Trust producing aspirational spaces for teenagers whilst undergoing treatment in hospital, we're looking to find a new logo that will work for both sides of the business, as yet we don't promote into the health sector but our plan is to in the next 6 months, I want to get some quick fire creative ideas without anyone spending too much time on research and ideally without viewing our website to see our existing logo to avoid any corruption of the creative thought process. Our logo needs to say... Current, dependable, efficient design led. I look forward to seeing what you can do in an hour.
