My flat rate of $80 is only for under 1/2 acre.
I'm pretty much done with leaves this year but as far getting more productive the leaf vacuum really did help but emptying the box we built on my truck was a real pain. It packs so well that its like a brick wall and takes about 30 minutes to an hour to get it all out.
I think next year I'm going to invest in a dump trailer. We saw a guy dump in less than 5 minutes which is much more reasonable in my opinion.
