Customization Big ask for help re: Photoshop

Hi all,

I am trying to help put together a new website for a local swimming club. The club does not have any funding so cannot pay a pro to produce anything and all coaches, etc work free of charge.
I have dabbled a bit with a couple of websites but am no expert.
The current site is www.fastswimmers.co.uk (You can see it needs some serious updating!) but as I am the only one semi capable, the task has been handed to me.

I have downloaded the free template called "music store template" on page 3 of the templates.

My understanding was that you can edit the photoshop document and that the css will take the information from the photoshop document. After a good few hours of trying to edit the photoshop pst, I discovered that this is not the case doh!

I have read some other help requsts on this forum regarding editing photoshop documents with the slicing tool on imageready but just cannot seem to get anywhere.

I know that this is a big ask but is there anyone who can help?
I can email the photoshop document to anyone who is interested in helping.

If no-one can help directly, can anyone explain in very simple terms how to go about converting the pst document to an html web page?

Here's hoping,

Thanks,
Ross
