Here is my logo for your consideration. I combined the gear and the lighthouse ideas into one, with the top bulb of the lighthouse being an "AM" for Absolute Mechanical. I also used only shades of green, as you are an energy-saving, green company. Additional layouts to follow...
Let me know if you would like me to make any changes to any of these, and I will be happy to provide.
Thanks for looking.
