Regardless of your level of expertise, it is always possible for you to do your own wordpress installation without having to spend money hiring a coder who you may not afford at all. You should be careful though with what website you refer to for tutorials on doing your own wordpress installation because the script underwent numerous upgrades and continues to be updated very often.
So, you need tutorials from a website that provides information on installing the latest version of wordpress as opposed to an outdated version. This is because you are not only going to be installing wordpress, but you may also want to learn about all aspects of customizing it so that you can have a system ready to promote your content.
If you are only interested in a WordPress development service, you can find many sources of tutorials. But you should ideally learn all aspects of development and customization so that you can get accustomed to doing your own website setups. However, if you do not have time for it, you should by all means outsource it. It is a good idea to outsource website development if you are looking for a professional outcome which you can use to build business based websites.
