Design a logo for DMV Advisory Services

DMV Advisory Services is a new consultancy that specialises in designing and delivering operational efficiency improvements projects for clients in the water and wastewater sector. DMV Advisory Services does not sell widgets, it sells consulting services, so the logo does not need to reflect an physical asset. Some points to consider: "DMV" are just my initials so they have no specific meaning to the services provided. Key words for consideration when thinking about the logo are: operational efficiency, water, wastewater, business transformation, organisational change, business improvement. I used to work for Hawksley Consulting ([login to view URL]). I liked their logo and colour scheme. I can't follow that too closely though as it will be seem as copying. I also like John Ringham Advisory Services ([login to view URL]). Again, can't follow that too closely either. Please note that this project is only for a logo. However I will be requesting a website in the near future.
