Master Template Creation from HTML Codes

I have two sets of HTML codes and need a skilled developer to merge them into a single master template.

The ideal candidate should:
- Have extensive experience with HTML
- Be proficient in Visual Studio Code
- Understand how to create a master template

The merged code should contain:
- Header and footer
- Main content area
- Sidebar

I have both codes written, I just can't get them into one code.
