Trademarks?

I have a client that wants his logo on the website and t-shirts he sells trademarked, should I go with legal zoom or is there something cheaper/better?

I’ve used them for my LLC and it went well

anyone have experience with this?

Are the tshirts going to only have that logo on it?

Or other graphic tess? If other, I think that would fall under copyright as long as there is some design to it them.
