New logo for Australian mystery shopping company

We are an expanding Mystery shopping business in Australia. We have been running for 7 years and feel as though we will benefit from a more professional logo.

Mystery Customers Pty Ltd

We are looking for a new logo for repositioning of the business. We are also currently developing a new web site and the new logo will be used for the web site, business cards, letterhead, brochures, marketing materials etc.
In terms of corporate direction and placement, we want ourselves to be perceived as modern, cutting edge, professional, innovative, and dynamic.
Our existing website is http://www.mysterycustomer.com.au which is to be completely revised but shows exactly what we do.

• Creative, classy, and have a fresh look with attention to detail
• Strong, bold, and leaves a lasting mark
• Not just plain text - icon or symbol is OK
• Professional
• Contemporary
• Open to colour suggestions
• Supplied in high quality vector format. Able to be used for all the above purposes.
• Logo must look good in black and white as well as colour.

• garish colours
• cartoons
• clichéd designs
• copies of other symbols that could offend copyright / trademarks etc
