INTERNATIONAL COPYRIGHT LAWYER TO RESEARCH ROYALTIES FOR LITERARY REFERENCES IN A NOVEL

I am an independent author looking to self-publish my historical novel, in which I have included several quotes and references to poetry & songs of the past (mainly 19th and early 20th century poetry and 1930s 1940s songs). I would like a professional to research whether royalties need to be paid for these references and, in case that's the case, to mediate so that I can acquire the license to use them. Consultation on international copyright for my own historical novel is also desired. Please, bid with the approximate fee you would actually require for such an assignment to save us both time. I attach a WORD file with the references in question for your information. Thank you in advance for your time and consideration.
