How much do drummers earn in the west end?

I am a professional drummer who is hired to play in a popular underground hard rock / heavy metal band. When I was 20 years old, I started at $500 - $600 a week on tour. Now 26 years old and more experience under my belt, I make $1,000 a week. I get paid $300 - $500 a week for rehearsals, minimum 3 rehearsals a week. For recordings I make between $250 - $400 a song, minimum 12 songs. Thanks.
