I taught myself how to hand-code my website, but there are easy user-friendly software programs out there that you can purchase. Or you can hire someone to create your website for a small fee. I spend $25/year on my website, but I invest my time in updating it and maintaining it. I recommend hosting it with www.doteasy.com. I have used this hosting service for six years or more and they've been great in meeting all my needs and offering more as technology increases and advances. They have great tutorials for first-time website builders.
Your website presentation could be your first impression as a serious writer.
