Desired website builder. Myth or reality?

Question

User interface

I have been in IT since childhood, but everything is somehow closer to the core, so it became necessary to use the help of the audience.
Hello. So a brief summary of the question:
There was a bomb idea, for the implementation of which a website with the simplest architecture is needed.
Landing page + 2 pages and a payment system that is ready to accept payments all over the world both from phones and from VISA and MASTERCARD cards. It seems to me that for the implementation of this website it is somehow not solid to hire a guru.
Therefore, with all my complete incompetence in the matter of web development, I decided to conquer some website builder. Buy a template to your liking and recreate the perfect design from your subconscious.
Advise the builder and in general according to the situation, or maybe the developer is better.
