How much should I expect to pay to have 40 feet of fence installed?

New home owner who has never had to hire a contractor before. Want to have chain link fence replaced and want to have put in white vinyl fence to match connected town home.

It is just a 40 foot length I need replaced and will need to have one gate. As I get quotes, what kind of price should I expect to pay? What's considered fair and what's considered a rip off?

EDIT: Thanks for all the feedback! I think I'm not in the right tax bracket to hire people to do this, so probably going to try to do it myself.
