Hello,
I am a 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 went through your requirement. Having worked on so many LaTeX books, I can help you bibliography appear in output pdf.
I work for US client as latex helpdesk and help modify latex environment/macro. I also create cls/sty as per requirement.
We can talk on price and schedule if you invite me for the project. Looking forward to hearing from you!
Best,
Shashi
