Moving to SSL page with https

Currently my site is http://emptymindfilms.com and my host set up a SSL but this is at https://secure.emptymindfilms.com
I am trying to get the checkout page, http://emptymindfilms.com/checkout to now be https://secure.emptymindfilms.com/checkout. I am running wp ecommerce plugin.

The only solution is to set the entire site as https which is what my host company did, but I do not want this solution. I tried the admin SSL plugin but this is not working with wp2.8 and I could not even test to see if this would be a possible answer anyway.
Is there some way to redirect my checkout page on to the secure page and then all links will go back to the http site?
Thank you users.
