Hello,
I am a desktop publishing professional worked for keyboarding and typesetting many scientific and technical books in latex using scan/handwritten document.
I have about 15+ years of experience. I have worked for many US and UK publishers on LaTeX books. I am science graduate with chemistry (Honors) and physics, math, english as core subject.
I went through your requirement. Having worked on so many LaTeX books, I can assure you of well coded tex files, pdf created. I can do justice to maths/equations as I am well aware of latex symbols and commands.
I have working knowledge of Illustration as well and can help you create figures, if required.
I worked for US client as latex helpdesk and provide solutions in generating multiple indices like subject, author index in latex.
I can communicate in english as desired in both written and spoken. I usually write about 30 emails daily to my authors/client in US/UK.
I can create a sample file if you desire so. If you want to compile it on any available latex template (cls/sty), I can do that for you. Just let me know. We can talk over price based on complexity of the book. I would like to assure your of layout, text, equations and symbols.
Looking forward to hearing from you!
Best,
Shashi
