My company works within controlling, currently primarily as project controls consultants on major construction projects but we plan to expand to also cover business controlling shortly. So the area is finance and cost management related.
The companys official name is Emil Borin AB (equal to my name and Inc.), but I have just purchased the domain www.controlling.nu and think that is a better name to use. I have made a go for a logo myself, but need some professional assistant, it might give you some ideas. Regarding colours I am using different kinds of blue and grey.
