A domain name and web site

I am going through the motions of establishing a web site with a domain name. The domain name was a name that is suitable for my company. I got the domain name from this web site. The web host is from this web site. It is all a bit confusing for me. However in due course I am sure I will have a greater understanding. I will have to find somebody to build the web site for me, I do not know how much this will cost. It strikes me that a web site is a very useful thing. I will have an e mail address with this very nice domain name. For me this is all a learning process, if I write about it in this blog maybe somebody else can learn from this. All suggestions about how to go about this are welcomed !
