Inking is a skill I never really picked up. You need to know shit about what line widths to use.
I can't do color, either.
Inking is quite easy. Just place more pressure on the areas where there is more weight pulling down. (Folds of slacks, fingers, hair, nose, etc.
It only looks horrible when you overdo it or when you do it incorrectly.
I used to have good pressure when I vectored everything, but freehanding pretty much took most of it away. It doesn't look too boring if the lineart is detailed, though.
And I wish someone would just teach me to color. I can try, but only get average results.
But yeah, if you can't lineart these, get someone to. It's really good.
