Hi!
I have more than few design concepts for you (#34, #35, #36, #37, #38, #39 and compact design in emblem form on #40).
I was trying to avoid using just initials as a focal point, because they are so overused/generic and will just "drown" your new visual identity in ocean of similar designs,...additional graphic element, visualy presenting actual work you do, on the other hand, will make a differnce and make your new logo look unique and recognizable.
All my designs pro and contemporary looking, but I would draw your attention to concept on entries #36/#37, with subtle hint of two nails, connecting symbolic planks, and creating overall building/house shape,...it is on one hand abstract/modern design, but with very direct message about the work you do! Hope you'll like it and feel free to suggest improvements on any of my designs! Thank you!
Regards,
Bojan Bundalo
