I have sold the database before, to a few people, for around $20. You will get the website, domain name, and the database - which means you could resell the database to others if you choose to. When I sold the db, I also included some generic pages to demonstrate how to access the data. Those pages can be found here: http://www.healthtopiclinks.com/db/.
I never put any effort into advertising this site. It looks like Google has 650 pages of the site indexed. Revenue from AdSense has been minimal. With a little work, the site could make more money then it has, but I have not been interested in putting much effort into it because of other projects.
The MySQL database is about 4MB. The site is written in PHP, but it used .htaccess redirection to appear to be simple HTML files. To run the site, you will need PHP, MySQL, and the ability to modify .htaccess.
I am asking $125 for the site, domain, and database. I will only accept PayPal payment.
Please post SOLD if you wish to buy, and then send me a private message. I am not selling just the database right now, so either you take it all or nothing.
