"Someone" is always one word when it refers to a person. The only time you can write "some one" is if you are trying to say "approximately one" (e.g., "Some one thousand people attended the festival."). As for your sentence itself, it doesn't make sense: does someone have anything to do with his own skills, or another man's skills? "Anything to do with skills" is very unclear, too--did he develop those skills? does he have those skills? Sorry, but it's a very confusing sentence.

I think you might be confused by the inverted/flipped word order. When you ask a question and the word order changes (subject auxiliary inversion or Aux inversion is the technical term), you should practice, uh well... What I'm trying to say is, it will take practice to know with confidence that you conjugated a verb correctly. And correct conjugation will help you form the question (interrogative) form of the sentence. Here are some examples. a) A has B. --> Does A have B? b) A had B. --> Did A have B? c) A will have B. --> Will A have B? d) A has had B. --> Has A had B? etc. p.s. - "does someone has something" is incorrect!
