Transfer my website from a .com.au domain to a .co.uk domain

I need to transfer the content on my Australian domain (www.justafrica.com.au) to my .co.uk domain.

I know basically what I need to do, but want someone more technical to ensure everything goes smoothly. There are all the files on the server and a MySQL database.

I also need included in the quote the cost of changing the currency across the site from $ to £.

The Australian business will close at the end of October, so the job needs to be done then.

If you have any queries, please contact me. Look forward to your replies.

Best regards, Annwen
