That $50 dollar soap must be killer!
$40 for wear? You must be rough on equipment.
$30 on gas? I know fuel is expensive right now but sheesh!

More like $10 soap, $10 gas, $10 wear.

$150-$30= $120

If your doing this by yourself and can knock it out it in one or two hours(which you should be able to) then it would be a good account to start out with. If the dump's were going to be filthy then I would add that in. But 10 enclosed landscape trailers would be easy money.
