Website design

Hi

This will be my first web presence so I am looking for something fairly basic.
I would like to be able to update content myself in the future if that's possible.

At the moment, I am probably looking at only 2-3 pages but would like to build on that in the future if it is successful. I am happy to include a link on the site for the web designer.

The site will be used to sell a business service online but initially, I just want to include a link to paypal for people to pay once they have completed an order form where they will need to give detailed info on their requirements.

I'm not very well up on website design so I probably haven't included the details you need to be able to quote - so please ask a question if you need any more info.
If you can give me some idea of previous sites you've designed, or urls for samples, that would be helpful.
many thanks

I am a writer so the content isn't a problem.
