Place SSL Certificate on Checkout page

I have a website and am using woocommerce for the shopping cart (check it out at [login to view URL]) which is built in php and uses jquery for client side form validation in the checkout page. I host my website on my own server and because I'm limited on ips, I use a different port other than 443 over the ssl cert. I have the cert installed and it's a working, functioning cert. However, in my shopping cart checkout page, I can't get the cert to work. I need to expert in php and apache skills but also wordpress and understands how the wp framework works around ssl certs including how /htaccess and permalinks work. I need this completed by tomorrow afternoon (2/16/2012) at the very latest if not tonight!
