Need help setting up a website for charity

I need to set up a website for a basketball fundraiser we are having. Basic one page with event registration. We will do this once a year so the website will need to stay. Needs to be inexpensive and hopefully easy to integrate with social media.

Also thinking of using eventbrite for the registration and payment.

Need help selecting a host and domain registration company. Hopefully one that has good templates.

Thanks in advance.
