WordPress translation plugin

Hey, people, the company is trying to translate the site into English and they use WordPress. The idea is to have a united kingdom flag that when you click leave the entire page in English. (Obvious hahaha). I searched and saw about wpml, but found it very expensive here. Does anyone know of any other plugin that does this? A, and it is worth remembering that we have all the text already translated, we want to insert manually. We just do not want to have to redo the entire container again.
