Hello zhirong80,
This is qsajib71, an individual from Bangladesh, the real world all-round expert in LaTeX typesetting especially in transcribing theses, dissertations, reports, books etc. which include complex Tables and diagrams, from Word and PDF into LaTeX. I'm sure I can do this task efficiently and quickly. Please provide me with some of your PDF files so that I can give you an idea how many hours it could take me to complete the task. I can start the job immediately and I'm sure you'll like my work.
Please take a look on my portfolio here for my previous LaTeX work samples. Thank you very much for your time. I'm really very excited to start the job right now!
Yours sincerely,
Qutub Sajib
