What is the easiest way to create a professional online presence without hiring anyone?

As simple as possible without hiring a developer or using multiple ways.
what we are looking for is an all in one platform where you can: register a domain, set up a professional email, build a simple, clean website, handle basic security/privacy for the domain, manage everything in one place without technical knowledge. Right now it feels like most setups require stitching together separate services domain registrar, hosting, website builder, email provider, which quickly gets confusing for someone just starting out. There's something more streamlined that lets you go from idea to live business website in one system, even if it's basic at first and can scale later. For people who recently started a small business, what setup ended up being the easiest and least stressful to manage?
