Hi there,
Yes, with all the good type-in names taken, domain parking has lost its luster. Domain Development is the next big opportunity for domain name investors like yourself.
Here's a quick to do list for you to get started:
1) Set up Deluxe Hosting Account at GoDaddy. Deluxe Hosting allows you to host up to 25 database driven web sites on your single hosting account. Once you exceed 25 sites, you can just upgrade to their Unlimited Hosting plan.
2) Install WordPress using their Hosting Connection applications. GoDaddy's Hosting Connection offers a step by step walk through to guide you through the installation process. Its actually really easy. Drupal and Joomla are other great CMS (content management systems) scripts, but WordPress is the best for newbies. The designs and functionality are super professional and the installation and management is the easiest. There are some advantages to Drupal and Joomla, but for newbies / non-developers / non-programmers those advantages are probably out of your reach.
3) Once you get the 'framework' of your site up and running, you'll have to customize it and configure it. There are tutorials on the web and eBooks available to show you how to do this. There are all kinds of tips and tricks that can make your site look, and more importantly, function, like a professional web site. This includes integration with things like: Google AdSense, Google Analytics, Google Webmaster Tools, Auto Search Engine Submission, SEO Optimization, XML Sitemaps, Cache-ed Pages, Photo Galleries, etc, etc.
This will take a little bit of time for a newbie, but you'll be off to the races once you learn. And once you learn how to do these things, you can actually make a ton of money on AdSense. And that money grows over time as your sites gain inbound links and greater trust from search engines. Most of my developed names each used to make a few dollars per year on parking services like Parked.com, Domain Sponsor, and Fabulous, but now they each make a several dollars per day as developed sites. More importantly, because of SEO, my revenues are now growing, whereas before, on parking pages, they were declining.
4) Once the framework of your site is up and running you need to fill it with content. This might include you handwriting articles. But the better strategy is to gather free articles at places like EzineArticles or Constant Content and Helium. There are a lot of other sources out there for free articles. Another way to do this is to hire these articles out to freelancers at places like Craigslist or Elance or Odesk. Its important to develop different pages of content for the most popular keywords related to your site. You should use a keyword tool like Google's AdWords Keyword tool:
https://adwords.google.com/select/KeywordToolExternal
Type in your keywords and then write / acquire articles targeted at the most popular keywords.
5) Once you're finished filling your site with content, you'll need to start marketing it through link building and article marketing campaigns.
6) Be patient. Domain Development is not a quick fix. It typically takes 1 - 3 months before your site gets fully 'picked up' in the search engines. But once these sites are up and running, they're basically like little soldiers that bring back a lot more 'plunder' to their master than those pathetic parked pages did. And if you keep at it and you build lots and lots of sites. You can develop some serious 'passive income'.
