Hi Kicken,
I looked at the link you sent me about the things you'd like to sell. I wish I could tell you yes, but the reality is that it's illegal for you to sell products with the TKDspace.com name because you don't own it.
It would be like printing Coke or McDonald's on stuff and selling it for your own gain. It's just not legal and I can't allow it.
If you change the logos to something just generally tae kwon do related though there is no problem with that and I'm sure they'll sell just as well.
Have you tried CafePress.com? They will let you create a store and put your own original art and logos on stuff for free.
I've actually set up a TKDspace.com Online Store there myself.

Thanks for checking with me,
