Start with selecting a template. Before you select a template, think through the sections you need, homepage, about, galleries, testimonials, contact. Does that layout and design align with your vision.
Buy your domain name. GoDaddy is reliable and straightforward.
Then start slow. Don’t try to build everything at once. Add your logo first. Then your homepage images, your best ones. Then your text. Move to your about page. Add a few testimonials. Then one gallery. You can always add as you go.
A simple website live today beats a perfect website that never launches.
