Hello,
I'm a U.S. (San Diego, California based) IP attorney and I've worked with my clients with their U.S. and foreign trademark matters for over 20 years. My bid is an estimate only. If you can provide me with your application / registration number, I can review your trademark information and give you a better idea of the cost involved. There are some limitations on selling registered trademarks so we would need to discuss those limitations.
Best regards,
Michael
