Hi, here are some logo ideas for your company. I've gone with the keyhole in the bottom of a lock as the main graphic of the logos. The keyhole is in the shape of an R to represent "Roper." I liked the subtle approach to the graphic, in that it can read as a lock hole, or just a nice R logo. but it's not too heavy handed as being a lock, or a box since you are trying to not pideon hole your business into that one market alone. The one with the outline around the entire logo is meant to represent in a subtle abstract way, the "box" in lock box, or a house shape as well with the slightly peaked roof.
I've submitted a few versions showing both different looks as well as different treatments of color usage. A one color that would be used on pens, notepads etc, nice a bold and still legible at a small scale. I've tried to pull in the bronzy look of a lock into the other designs.
Hope you like one, thanks for looking and taking the time!
