Need Design Pattern Suggestion C#

I am learnig Design Patterns, I need some recommendations. Need to construct a PDF using Aspose, For constructing PDF, Data is acquired From differrent services i.e Cover Page , Table of Contents, Section 1, Section 2 and so on. For Cover page,Table of contents i have a plan of having it as a seperate service, and similiarly other Section 1 and Section 2 , ending up having different serivces on its own.

Initally I had a plan to use Template pattern to construct the steps for constrcuting the PDF - > but not quite sure, if it sounds fitting. Need suggesstions !!!

Important : User can decide the Contents of the PDF, based on their selection i would construct the required section and will add it to PDF
