Here are some of my concepts. I've gone for something that's fairly clean and simple, yet striking. Creating an icon that works well within the logo or as a stand alone element, one that can be used for things like favicons or watermarks.
The logos are 100% vector so will scale well to any size, and works well in full colour, B&W and on coloured backgrounds if needed,
It would be my pleasure to work up any variations so please do say. I look forward to your comments or thoughts.
Thank you for your interest in our contest. We are working with the idea and like a lot of your entries. We'd like to offer free reign to the GD's submitting for the job and if you'd like to use any words that encompass our brief please do so. We aren't committed to Pinnacle so if you have a phrase or set of words to encompass Professionals (Doctors, Lawyers, Accountants ETC) please do so. I look forward to your submissions.
