Hi,
My name is Zeljko and I am have more than 25 years of experience in LaTeX, DTP and printing, and I think that you are going to find me qualified for this job if you take a minute or two and look at my portfolio, which is publicly available on Freelancer.
Also, you can take a look at some of reviews that other clients left. I am 55 years old and I take my job very seriously and responsibly.
During this period there is almost no type of book (more than 1000) or article that I have not done, so your requirements are very familiar to me. If you find that my skills are good enough for this job, I would like to do a interview with you. For any questions, I am at your disposal.
I also would like to add that I already did a lot of material on different languages like Spanish, German, French and Portuguese along with English.
Best regards
Zeljko Hrcek
