Build me a website with email accounts but which can not be traced back to me (Market research project)

I am looking to create a website and linked email accounts. This will be used for some anonymous market research for a business I am thinking about and therefore it is essential that it can not be traced back to me personally. When I have tried to build through WIX and other website creators it is essential to put my personal details which can obviously be traced back to me.

The website itself is very simple and I will provide all images and text and should only be about six pages or so.

If anyone could advise or assist please let me know.

Thank you.

Best
A
