We think your design number #19 is close to what we are looking for in our logo!!!
1. We like the fact that it shows a very simple stylized house (which is where we work) 2. That it is '2 C T R L' rather than 'Two control'
What we would like to see a different font and a bit more spacing between the letters. It needs to look somehow a bit more expensive and luxurious. And the letters ctrl need to be in capitals like CTRL.
really sorry for late respond, i have trouble with my internet connection recently. Here my update for consideration, i already try to develop #19 concept and try update as your request, but it seem don't work with all caps letters(CTRL) so i decided to develop with new idea.
