Paddyboy99,
The previous posters are correct, design is important. Good content is vital.
If you do hire a developer remember that you will need to have your site updated regularly so it would be best in that instance to use someone local or easily available/contactable.
If you want to build the site yourself you must have good image editing capabilities and a good knowledge of HTML and CSS at a minimium.
Wordpress is the best platform for many sites that will contain frequently changing content.
Large sites that will require an online store or other functionality may require a more powerful platform like Joomla.
I prefer to use Wordpress but you don't need to use either or any CMS at all.
Think about accessability (mobile browsers, old browser like ie6, etc)
Make sure your site loads quickly (optomize and minimize images)
If you need advice while in the midst of this process feel free to email me/pm me.
I am not a professional web designer but I have previously done:
ocl.ie
yourmemories.ie
and I am working on blackrath.com.
I am sure you can learn to build a good site and in the process you will learn how to edit and update your own site.
If you give a shot and don't like your results you can Hire someone local to you and you will be able to discuss the issues from a more knowledgable position.
Best of Luck
Regards
