Dog Training Logo

I am looking for a professional quality logo for my dog training company. I would like something that is cartoony, but has lots of attitude. I'm envisioning something along the lines of a cartoon dog that looks similar to sonic the hedghog. It should be suitable for letterhead, business card, vehicles, etc. The bids need to include a mockup or at the very least a VERY strong portfolio. Upon selection of a designer, you understand the following: - an acceptance on this project DOES not mean we will accept your design. A design will be paid for ONLY if we use it - payment will be made after work has completed - you must deliver no later than 3 days upon our acceptance of project - we require at least 3 "re-designs" of the original design. - upon completion/payment of this design (assuming we accept), you must provide us with the rights to the logo, including all PSD and images used in the design.
