Hello,
I'm an Italian native translator and I'm a Project translator editor for WordPress. So, I translate daily .po files with HTML code inside.
I can translate your text in 1 working days. It would take 3 hours between translation and proofreading of the text to deliver an error-free text.
To answer to your questions,
1. What is .mo files and what tool do you use to translate it? → It's the same file as a .po with the difference that .po file is easier to read for humans, and .mo file is easier to read for computers.
2. When you can start and how long will it take to finish. → I can translate it in one day, it will take 3 hours.
3. The price. → My rate is $ 50/hour and it will take 3 hours to translate and proofread your text, and be sure the HTML tag are correctly set in the translated version. So $ 150,00
Since, the delivery is in the same day the payment is upon the acceptance the project.
Please, fell free to contact me via chat to have my WordPress translation portfolio, and to discuss further details, but don't redirect me to WhatsApp, Telegram or similar. I work here on Freelancer.
Best regards,
Cristina
