logo of Corporate Concierge Group

I design a logo of company which name is "Corporate Concierge Group". Company parameter was: 1. Within all designs the logo should sit on a white background only. 2. We would like to see variations of our logo as such: Our acronym for our company is "CCG" so we would like to see some logo designs that only contain the acronym, as well as logo designs that contain our acronym as well as the full spelling of our company within the logo, and lastly some logo designs of the full spelling of our company name without the acronym involved. For example we would like to see some logos that contain: (CCG & Corporate Concierge Group) , logos that only contain (CCG) and logos that only contain (Corporate Concierge Group). We are a corporate services provider and the logo must be very corporate while still having some "edge" to it. It should be clean and able to trickle down to letterhead as well as business cards, etc. Some buzz words we were thinking were (Corporate, Edge, Polished, Prosiness, Respectable, Capable) . We also tackle most of our corporate solutions via software, so that is where the "Edge" comes in, in our industry, and we do not wish to have a "stuffy" logo. Something clean on a white background, simple, but not too simple where the branding of the logo is lost. This must stand out and contain something unique where we can begin to establish our branding from.
