Describe the site it's going to be if someone buys it from you.
How much money is there in that project for them, realistically?
Teachers in the public school system probably don't need a website at TeachingCareer.com. They're surrounded by teachers even before they get jobs -- while they're still in college.
Maybe teaching overseas? But do established businesses need this domain? Only if their domain is horrible -- then they might want to upgrade. But this domain won't be their only choice. And how big will their budget be for a new domain?
If you follow this line of reasoning, you'll probably come up with other ideas for usage. But the budgets involved won't be large typically. And the likelihood of anyone needing this domain is fairly low.
Price it in the low $x,xxx and wait for a buyer. You may end up settling for less, or you may never get any inquiries.
