Is it harram to hire an Escort?

I'm new to the religion and actively reading the Quran. I wanted to ask. Is it harram to hire an escort for spending time with you and having sex? She's not part of a brothel, just independant. Also, I'm engaged but my wife is many countries away, and something makes me feel like this would also make it harram, is that true? sorry for asking such dumb questions.
