I recently sold all my Bitcoin.

> can you run a node from a van?

Yes but it will probably be slow. 


> What is the best way to do this? 

You could try with Starlink or something and see how it works. 


> I have a node  which I got from nodl years ago is that still good to use?

Yes, that should still work. 

> How can I get paid in Bitcoin for ticket sales?

I would use a service called Geyser (https://geyser.fund) to get started with selling things for bitcoin. That gives you a unique URL to send people to, a lightning address to receive lightning payments for tips, and a full suite of tools to grow your business.
