Hello,
I am a latex publishing professional worked for many scientific and technical books.
I have about 15+ years of experience. I have worked for many US and UK publishers on LaTeX books.
I went through your requirement. I can fix it fairly quickly. I need complete application file i.e., tex files, cls, figures etc so I can compile and fix.
I provide help to authors as latex helpdesk executive for a well-known US publishing house. Do let me know if you have any question!
Looking forward to hearing from you!
Best,
Shashi
