A website I use a lot for cursors is www.cursors-4u.com. You can take the css code and post it to your page like you would your layout codes. Using that same basic code, you could probably just replace the image with something else.
The most popular cursor site is Cursors-4U. You need to find a cursor you like and underneath the image there should be a copy+paste link for it. Paste the link between the (' ') and it should work :)
If you cant find one you like, you can create your own and upload it to a cursor site and follow the same steps
