It depends what your doing.

If you have a domain. I would install WordPress.

Now if you don't have a domain WordPress.com offers a WordPress and hosting but that is a bit more expensive, but it is simpler than configuring the domain yourself.

Now you can buy a plan and install plugins and stuff then but I reccomend just using WordPress.

For something like SquareSpace or GoDaddy it depends if you want to pay or not.

My favourite is WordPress.

But...it's up to you

First you need to prepare a plan or a guide and follow it clearly. Can you take this as an example web design process

Can you advise us really good specialists. Who would make a really cool design that would make users think about the purpose of our organization. A design that evokes emotion. And users would stop at certain points and not just flip through the site.
