First of all you need an agent.
Secondly you need to prepare yourself for a lot of rejection. It aint going to happen over night.
One of my best mates is an actress and she is still going to auditions and getting knocked back. She's been in a couple of adverts and teaches drama but is still holding out for her big break.
Only one in a million makes it big. Just keep that in mind.

Good luck and with determination you will eventually succeed.
