Hi Sir, Good Day, I studied your detailed brief, then I think the unique idea for your logo, According that I create some logos here, that means not only a symbol, its will depict the meaning of your activities. You can read easly 'LD' in the dent element. I hope you will like this designs and its will reach the idea in your mind.
Feedback is really an inspiration for new uniqu ideas. Font style, colours and concept will change according your comments Yours truly. K_Chemnad
