First, let me point out an alternative. Keep the Varrock teleport for Varrock center, and use the Ring of Wealth to teleport you to the Grand Exchange.
If you really want the Varrock Teleport spell (this includes the house portal) to take you to the Grand Exchange, you must complete all the easy Varrock tasks, then talk to Rat Burgis. You'll find him next to a broken cart, south of Varrock.
yes, outside the big bank near the grand exchange
To look for a place, like Varrock, it is best to use the World Map. Click on the map icon near the upper right corner. On the map, south-east is down and right. Outside the map, make sure north is up (check the compass icon), to make the directions the same as those of the map. Eventually you can get Varrock teleports to get there. If you are a member, you can use a Varrock Teletab, or the Ring of Wealth to get directly to the Grand Exchange - a popular destination in Varrock. Both members and non-members can teleport to Varrock using runes, but you need to have a certain magic level first.
It teleports you to a Pokémon Center or if you're in a cave it'll teleport you outside of the cave.

You can mine it in varrock mine check the world map it is right outside varrock. By turning clay into soft clay is a very easy way to make money.
You'll find out this years event outside the cooking guild - varrock.

just outside the south entrance with a bunch of dark wizards around it
It actually is possible. Once you have completed all the easy tasks for the Varrock Diaries, speak with Rat Burgiss. The new teleport will bring you just outside the entrance of the GE.
