Both are correct (but there's a typing mistake, it's "Ich brauche (!) jemand(en) ...").
Both "jemand" and "jemanden" are possible in both sentences (in general, you can always choose one of those, but "jemanden" has a better rhythm here).
The first one with the Konjunktiv is more polite. The second is very direct, and states a fact.
