Creating site, tips?

Start by creating a free site at Wordpress. Don't steal images (you can get free, public domain images from NASA so you won't have to). Give it a few months and see if you like it before you buy anything or commit further.

You can create it with Wordpress or Squarespace, if you are new there are a lot of videos that teach how to use it, it is not that difficult. Then get a host and get a domain name. To protect the site also you can get a cheap ssl certificate and you are done!

It's easier to make than to say by words! good luck with that!
