In practice how does the état des lieux happen

Hello, I am very close to signing a contract to rent out my apartment. The lease should start on 1 July, so the time is short. Hence my questions: 1. Can the état des lieux be concluded in one go, or does it take days to produce the final report? 2. How long in advance should it be arranged? Can it happen within 1-2 days? 3. Can you recomend an English speaking expert/company, who/which would do it professionally and for the standard price? Thank you!
