Upon successful completion of a web site Hosting for that site will be required.
There are a few things to consider.
1. Do you require a 'Domain Name' for your site?
2. Does your site employ special features such as Frontpage Extensions or     Streaming video?
3. How much web space will your site require? (mb)
4. How likely are you to need Technical support from your hosting company?

Domain names

The usual thing to employ here is the website company name and to decide what sort of company it is.
Most commercial companies will choose a domain name reflecting their 'trading' status and go for a .co.uk (if British) or .com (for larger, more international commercial concerns), there are other types of domains such as .biz that may be considered.
The important thing to remember is that the domain name will (or should) reflect the company image.
Not everyone has a company so in choosing a more Personal domain name might be more appropriate.
Eg: .me for instance.

The cost of a domain name does vary. Approximate charges are around £5.00 per annum for a .co.uk Domain
around £15.00 per annum for a .com
(Like any costings, shopping around is always useful). Domain name registration is usually for a two year period.

Domain name Availability

Is your domain name available? For example if you wished to register a domain name that already exists you would most likely have to select another name for yourself. (Tesco.com for example!)

Let's now assume that you have chosen your domain name and that it is available. Ok. Great! Now you pay for this and this domain name is yours for a usual period of two years. Thereafter you must update your registration to retain.

So you now have your domain name paid up in full and you wish to set up a hosting account that you can apply your domain name to.

Most hosting companies will be able to sort out the domain name registration for you. Sometimes choosing a good hosting company first seems logical.

Hosting

This is where you will upload your web site to in order that everyone may be able to visit your internet pages.
Host computers are permanently connected to the internet allowing everyone access to your uploaded site.
(Although, if your site has a lot of 'traffic' you will end up having to incur higher costs for additional bandwidth).

As there are thousands of Hosting companies available this is where your own criteria for your website come into play.
When researching hosting do ensure that the hosting company does actually provide the facilities that you require for your site. (I always view the potential Hosting company's 'Help' files section to ensure help is forthcoming and available before committing myself to buying from them).
In the case of Frontpage users; Does the hosting company permit you to use Frontpage extensions? If they do not, move elsewhere.
What about the use of additional scripts such as perl or java? If required, check the hosting company can accommodate these scripts. (This is the kind of information that may be gleaned by searching the help files).
If you require a Streaming server for broadcast video, does your hosting company provide this facility?
(Expect to pay high monthly rental charges for this facility or for e-commerce).

Hosting is as much about your needs as the cost of it. There is no point in paying for a top of the range facility if your website is aimed more at family and friends.

I calculate that the average price per megabyte of webspace for hosting is around the £1 per mb (per annum).

So I have a 20mb website that I wish to host, I can expect to pay around £20 per year to host it,
(Sorry, but a streaming video enabled or e-commerce host would not come into this category!)

Technical support

It's surprising how often we require this facility. Consider if it is provided, is it effective? Very important to have referral with an expert when uncertain how to get that form-email operating! Look carefully at what hidden phone costs may be involved too. (Again, the Help files will reveal much about the quality of support).

Once all these factors have been considered then it's simply a matter of signing up, paying the bill and utilising the account information to publish your website with it's new domain name to the host.
