Make Visible to client

Please help!

Just a heads up, I am very very new to all of this 🙂

Here’s the story:
I have developed my client’s WP site off site on my computer.

I have then made a subdomain within my live website to host the client’s website for them to look over: webdevelop.mysite.com. I have uploaded WordPress, and all of that, so I have a blank WordPress canvass.

So — what files do I need to transfer over to webdevelop.mysite.com in order for it to look like the website that I have made off site, so the client can look it over?

I am hosted on GoDaddy, and am using a PC, windows 7 if that helps.

Thank you SO very much in advance!
