Looking for someone to make a script

Hi im looking for someone to make me a quick script where when the player walks into trigger x it loads up a level and places them at the correct spot an example is if you walk though a castle entrance it loads level “castle” and the players position is x x x where the entrance internals is and when they leave the entrance they appear back outside at a set position outside that links to the exit/entrance they came from
Another example is going though portals to new levels or between landscapes which are separate levels

Can anyone help me on this?
