When I started
I started working for someone else in 1997. Very large local company that paid me $7.5 to start with no experience. Over 4 years moved up to $12. I was summer help only (4 months) while I was home from school. People who worked year round got paid slightly better, and had benefits.
That was 8 years ago, but the company also paid more than average at that time. I would say for a younger, brand new guy: $8 to start. With good experience, start at $9-10. And, give raises as they prove themself.
