Hiya Joshua, you must be the youngest 'Luvvie ' on the site. I work in TV & in my experience casting directors/producers often look for their talent from established stage schools ie. Sylvias Youngs, redroofs etc. Lots of these schools run weekend courses aswell, certainly when you are a bit older you'll find that the likes of Grange Hill, Eastenders etc contact the schools with their requirements, then lots of people go for Auditions. Good Luck, Keep at it
