Another way you can go is to create your own templates. You can base these around the types of articles you enjoy or you can visit other directories to see if you can find a general idea that gives you the ability to come up with your own template. Using your own articles may help you come up with your own templates as well. If your articles are along the same lines, you should be able to come up with a number of templates. Those will give you ideas for new articles and that for sure will help you get through your writer's block.
The first time you make a WordPress site it may be a bit tricky for you. If you are not very well versed in PHP and MySQL this site can be all but downright confusing to you. Taking it slow and learning to tap into the functionality of WordPress is ideal however and will immensely benefit you in future sites, therefore you should really consider tapping into it for one site at least to see how it benefits you.
