The teacher gave us these the other day. He's done about 15 movies and countless commercials so i guess he is a quite reliable source.
Tv Documentary $5.000 ~ $8.000
Australia Feature Film $40.000 ~ $60.000 ( While retaining ownership in Australia )
American Feature Film $100.000 ~ $300.000 ++
Training Video, Late night Tv ads , Abc educational Tv ~ $3000
Tv Ads - $10.000 ~ $25.000
So...... GO FOR THE TV ADS. 30 seconds of music, around 15.000 bucks... not bad!

Music budget is usually 3% of the overall
