Set up a WAN connection

I need everyone expertise on how to set up a WAN network. I’ve never set up a WAN network before and now that my company have a project for me that need connection from two different location together (between Corporate office and Remote). Corporate office consists of about 60 users and Remote office consists of about 40 users. What is the first step to plan this WAN network? What hardware and software do i need? I’m kind of new as a Net Admin therefore i really need step by step how and what i need to do to achieve this project running smoothly. Thank you for all your help in advance.
