Logo design

I needed a logo for a new project announcement and to save time, developed one myself. Now I seek a more professional Logo that identifies a professional icon of what my company does. This is the first assignment of a multi-part corporate identity project, to identify capabilities of professionals claiming to be professionals at developing awesome corporate identities, following up with exciting WEB sites and other illustrative efforts. There are two requests: a) would like a high definition illustration of the “S” graphic shown in the attached sample, in .png or other format that can be quickly inserted onto letterhead, business cards, embossed on shirts, etc. with white to dark backgrounds; b) ideas of a totally new Logo that might better represent my goals. Please respond quickly with interest and ideas, and let’s get this project moving forward.
