I don’t know what you’re doing and what you’re really asking.
It doesn't sound like you read the OP.
You want a static site? Hugo or jekyll.
As I said, I was unable to find a theme that has all the design features of a builder like Squarespace. So to make a professional website with an SSG seems to require coding knowledge.
There are options for contact forms but it will require additional setup.
Yes, I mentioned that. Many of them are limited or costly:
250/mo for free and $8/mo for unlimited with https://web3forms.com/ is the best I've seen so far (besides the completely free one which I'm not sure about).
