You should definitely build up a list of potential end users for the domain. A few potential companies to add to your list have already been mentioned by 'domainicate' and if you want to get a much bigger list then use a free website called ZFBot.com and type in the word 'descriptive' and hit Search.
It will return 100+ domains that have the word 'descriptive' in the domain name. All of those are potential end users, but there will also be a number of those domains owned by domain name traders. And you can quickly find the domain name traders by looking at the Primary Name Server (PNS) for each domain.
For example if you see the PNS as sites like buy.InternetTraffic.com & ns.buydomains.com then these are likely to be domain name traders as they have parked that domain at those websites. So avoid contacting owners of those domains, if you want to get an end user price.
Just by entering the word 'descriptive' into Google and doing a search PLUS using ZFBot should give you a good 'starting' list of potential end users to approach.
And sometimes the obvious route to finding an end user is not always the most fruitful one so you need to get creative about creating as big a list of potential end users as possible.
Outside of the obvious approach above of contacting the owners of domains with the word 'descriptive' in their name you should also have a brainstorming session to see who else would benefit from this domain. E.g. go to Thesaurus.com and see other 'Synonyms' of that word and see if there any other words that could be plugged into ZFBot to pull up owners of domains that have a similar meaning to 'descriptive'.
Plus, look within the word itself and is there anything you can pull out that could also have meaning in a clever way to another company e.g. the word 'script' stands out as part of the word. Enter the word 'script' into Google and you then start to see products for 'Script'writing and would any of these be interested in your domain name?
And once you've drawn up your final list of potential end users, and although it's a pain, you should then visit each domain 1 by 1 and do a search for the relevant contact. Ideally you should get the email for the website/service owner, a marketing manager etc, although in a good % of cases the main person could be all of those people rolled into one.
It makes sense to do all your homework about the domain and how each end user could benefit from using it. Don't just fire out the exact same email to everyone i.e. try and personalize it so that you can maximize the potential for a 'bite' from one of the end users.
Hope that helps in some way, even if it at least opens up some different ways you should think about your domain name and how to lengthen your list of potential end users.
