Pages not displaying at all

HI! I am really struggling with getting all of the pages to show. I spent 5 hours on with my hosting company trying to figure out why the pages on the site do not show at all. My hosting company accidently made the site go live and now I have a site with a home page that will not link to any of the pages I have created. I am not a programmer and am not really that great with code (completely self taught) so I need a little hand holding.

1. I have tried following some of your directions to others and have cleared my cache and deactivated plugins that may be causing a glitch.
2. I have used the templates that you provided to make the pages in question.
3. I am able to see the pages both in the pages tab on the left side in WordPress and if I go to view the site and click on edit page. But no pages load on the site themselves only the header and footer.
4. The pages appear in the templates area but are not linking or loading on the site when I view it live only the header and footer come up when you click away from the home page.

I am seriously struggling and need some help. I do have experience with building sites and have never had this happen before. I would love if someone could help me as the site is live and it is for a business.
