Hi trueinnovation, welcome to Namepros.
My first piece of advice would be to visit the legal section and read all about Tm issues and the possible consequences.
Next I would go through your portfolio and identify any more domains with possible issues and see if you can get refunds on any offenders.
As has already been mentioned, Namepros has sales threads, and Sedo is a good platform, but will charge fees for selling your names.
Good luck.
