Powering over 100.000.000, Wix is the most popular website builder out there, not counting Wordpress, which threads the line between a CMS and a website builder.
Wix excels at being accessible, both from a user friendliness perspective and price-wise. It has one of the most easy to use editors and the next steps seem to be logical throughout the building process.
Wix also has very strong blogging and ecommerce features, and it's always adding more features. There's also a huge app store available, which can augment your website should you need any niche features.
You can hire a web designer that specializes in Wix, right from the wix platform. You can also see a list of their previous projects in the portfolio section.
There's a forever free plan available that is ad supported (the ads promote the Wix platform) and plans start at $8.50/month, free domain included.
