Most hosting sites offer packages like WordPress or SiteBuilder where you can choose a template and create your own Website within minutes. The hosting company will most likely offer you some assistance with this if you get stuck. Just have a look at your control panel for your website hosting.
There's also software packages you can buy that make creating websites easy.
Just remember that if you do have someone write a custom website for you - you are tied into that person, and if they become busy or unavailable you're going to find yourself unable to update your website, especially if they use software you don't own or don't know. If they disappear you have to start from scratch and get someone else to rewrite your entire website.
Also make sure they give you the design rights and copyright into what they create for you - so they don't hold you to ransom afterwards.
