Hello! I'm an experienced translator, native Spanish speaker (Latin America), and I just happen to be very good at what I do. As you can see, I have a good grasp in the English language, so translating from it to my native language is no problem. Since the document is about 30 pages long, then I can easily do 10 pages a day, with some extra days in case an emergency arises.
I understand that this an important task for you, and I do want to guarantee your satisfaction, so I propose to use the milestone system to show you the first ten pages as soon as I finish them. You can check if my style suits you and if my work in general meets your requirements. If it does, I will continue working as usual until I complete the project, and if it doesn't, then we can part ways amicably.
I hope to be a good candidate for your consideration, and please don't hesitate to contact me for further details about myself. Thank you for your time, and I hope you have a great day.
