I never go to any links that are not approved as being allowed to be posted.
Many links we get are for scams, not saying your link does this.
I cannot comment on what I cannot see.
When you visit someone's site, it helps to ask for permission to advertise what you wish to offer.
If you do sell it, you will probably be putting in lots of work to modify the site to the new owners preferences.
I agree with Steve and will not look at the site, since we do not post links, or unapproved advertisements, and this looks like it might be just that. I suspect Steve left the post intact simply out of kindness and for me to decide what to do, since he knows I have purchased and secured domain names in the medical billing and coding field before and developed, optimized and evaluated websites in this niche. Otherwise, it would have been removed already, I am sure.
Having said that, I will go ahead and remove the URL, since I do, from looking at the URL, now understand its intended target audience and your question.
To your question and to elaborate a little more on Steve's short reply: Some web developers just buy up domain names and develop the site themselves. It takes a lot of work and knowledge to develop a working website and when done the site needs to also be search engine ready and optimized to be found by the intended target audience on all search engines under many search words. Otherwise there is little value in the work, which typically takes weeks, if not months, or in my case, years.
Most developers are more interested in securing just a good domain name. However, if the content is well written and there are good stock photographs someone might take a developed site with the domain. I have registered my own domain names in the past, purchased a couple from others, and purchased developed sites which I have then changed. It all depends. There is a market out there, but this website is not intended to offer domain names. There are sites and forums for that, also. Therefore I've also removed your email and phone number you posted publicly. If anyone wants to know more, they can PM you through the private messaging button.
