Well, advanced
Java skills dropped from $50/hr to $40/hr locally, and there's indication that they're pushing for $35 or lower now. That's the employee compensation, and I usually figure on triple that as the actual corporate billing rate.
Ideally, your bill rate is going to be figured based on your expenses plus whatever sinfully high
profit margin you can gouge the customer for. Unfortunately at the moment, it's a buyer's market, and that means that means you take what you can get, unless you can offer something that's not a commodity service.
The US is not a homogeneous market. What you can expect to get in Florida is a lot lower than what you can expect in New York. The only way you can truly get your question answered is to study what's being currently advertised in the locale(s) you intend to target. And, ideally, to talk to actual contractors working in the area.
The secret of how to be miserable is to constantly expect things are going to happen the way that they are "supposed" to happen.
You can have faith, which carries the understanding that you may be disappointed. Then there's being a willfully-blind idiot, which virtually guarantees it.
