Sharing services with family members

without having to pay for two games or two online services?

You would have to set his console as your Home console in order to do so. https://support.xbox.com/en-US/games/game-setup/my-home-xbox

If you set the xbox as your home xbox it will ask if you want to share your gold services with your family and then let other members access the games on the account

Good news for you. An Xbox One allows membership sharing. That means that all members of your family can share the one Gold Membership across the accounts. This will not work for the 360.

When adding the accounts to the new console be sure to add them to your Family to ensure that they will have access to Live service on the console.

Game sharing is meant for sharing with a family member. If you want to share your games with a family member, you will first need to login with your account to your family member's console and set that console as your home console. Then you can simply
log out and anyone who use that console can play your games.
