Hello,
Unfortunately the above comment is the cold truth.
These names are not exceptional: 3 words, one with two hyphens. Tough sell. You can still develop them.
There is no scarcity of long domains. You should always question the value of a domain that is still unregistered in 2015.
At least these names dropped, they have been registered before. Somebody once paid regfee for them. But that doesn't mean there is a buyer.
sales-training-america.com => registered between 2008 and 2015, other extensions unclaimed

Good luck.
