I’ll make this one short and simple, about something I’ve learned.
Don’t try to design your own website from scratch unless you’re a website designer.
Use a template, or use a CMS. Otherwise it will not look professional no matter what you do or believe.
You might find the following Google Search query invaluable…
“creative commons” OR “open source” website template
And if you can’t locate what you are looking for, you can always buy a template for $60 and save your time and effort for something else.
