Turkish-English/ English-Turkish translation

We are a small womanswear company based in London. We would need a person immediately for approximately a month who could translate our English emails to Turkish and Turkish to English for the messages we receive. The messages are not very long, mostly a few lines and the language used is not very specialized.

The job starts immediately and lasts approximately a month. Please tell how quick your translation responses would be and how would you charge for your service?
