To host your WCF project (or anything in IIS, for that matter), it would be worth a read over Hosting in Internet Information Services. You can deploy your project by following the directions at WCF Service Publishing.
This physical path will be where you deploy your WCF project. Say that your host machine is named MyHostMachine. To deploy your WCF, right-click your project, select Publish...In that popup, select Publish method of Web Deploy, set the Service URL (ex: ), and Site/application (ex: Default Web Site/MyWcfService).
Note: If you have any permission issues that prevent you from doing a Web Deploy, then you can simply deploy to somewhere in the local File System, and copy the full contents from there to the application directory on your host machine.
