Site Tech - mark

Logo design for Site Tech Services, a Design Build IT company which specializes in Automotive Dealership new construction. They provide from Cabling, Networking to Cisco VOIP Phone Systems.
Client choose another logo from me but I especially like this one, even it's rejected.
Logo is maded by letters "S" which are forming unique and different mark. It also can be looked like an infinity mark when it's rotated vertical.
