Issues installing WP on Web.com

Here’s what’s going on:

Revamping, redesigning, and more or less re-doing my work’s website has become a new project for me. We would also like to begin using WordPress. We have an existing website (www.eastcoastaircraft.com) hosted on Web.com but I do all the maintenance and updates, etc.

Here is my question… the start of many so, bear with me.

Is there a way to install WP while leaving the current website active and running until I can get the chosen theme working together with our new content and other junk?
