No: "Is this sentence correct even though it's not that fascinating?"
No. The correct expression is "even though." Correct: Even though the assignment wasn't due until Friday, Ella decided to get an early start on it. Incorrect: Even although... Ouch, that's just bad. I can't even finish the sentence. But you get the idea. ;)
The grammar appears correct even though it is heard more like, "He is capable of doing this job."

Depends on how you are using it. You should start with even though. Or put even though in the middle

That sentence is not correct. I can't even tell what you are trying to say.
Babysitter is the compound word in the sentence "Their babysitter is dependable even though he is a boy."
