Estimate for basic 24' "good neighbour" wood fence

I plan to hire a contractor to build a basic good neighbour fence to mark my property line and provide privacy. The requirements are:

- no old fence to remove

- 24' straight run, level ground, sandy soil (loose, easy to dig)

- 6" gap along the bottom, 6' pickets, for a total fence height of 6'6"

- "shadow box" good-neighbour design

- framed with a top cap and a bottom cap

- pressure treated wood

- no gates

I got a quote from a fencing contractor for $2,130 (not including tax), which works out to almost $90/ft for a very basic fence design using basic materials, on a very easy to work surface.

Their quote seems unreasonably high to me. I priced out the retail cost of the required material (using 4x4x10' pressure treated posts, 2x4x8' rails, 2x6x8' top and bottom caps,1x6x6' pickets, cement, screws, delivery) and it was $712 (not incl tax).

This means that they are charging me for over $1,400 for labour, depreciation, profit, etc for a small, simple, easy job. This seems completely unreasonable. Everything I've seen on this forum indicates that a job like this should be about $45 per linear foot.

Can I get some comments from people who have had similar work done by contractors, and from contractors who have done similar jobs?

Thank You
