Convert a (Vitalsource bookshelf) to pdf file

Hello! I need a freelancer to help me convert a Vitalsource bookshelf to a PDF file so I can use it in Adobe or any other pourpose. Specifically, I am looking for an output in a PDF format that does not require any formatting to be preserved in the conversion process. The output file also does not need to be editable.
I look forward to hearing from potential freelancers and working together to find the best solution for this project!
