Pine Straw Install questions?

I have a client that wants an estimate for pine straw install, which I have never done.

I am thinking around 2,500 sq ft. so I am looking at between 125 and 150 bales?

I have a 16 ft. trailer, but 150 bales would take a few trips, so I am thinking delivery.

I baled hay for years, so are these bales easy to move/spread? Take more/less time than hardwood mulch?

How thick do you try to put it on?

Any advice would be great. Thanks!
