Change Oscommerce Checkout and integrate API for credit card billing

We want our SSL certificate installed in WHM. We want our checkout process modified so that it is fast. We want our credit card processing API integrated in our CRE Loaded 6.2 Standard. You will need experience in PHP, Javascript, XML, SSL? and osCommerce/CRE See details below ## Deliverables Our shop is very much live. We want you to install the SSL certificate in WHM/Cpanel, this must be done when we are both online on some form of messenger (yahoo, aim, icq). When you are finished the entire shop should be protected by SSL, so if someone goes to <[login to view URL]> they will be redirected to https:// and they will view the entire store in SSL mode. Once this is completed you will begin working on your own test environment to make these further changes. The process that a customer goes through to checkout must be modified, so that it is less complex and less time consuming (less steps) this is outlined step by step very clearly in a document called [login to view URL] in the zip file attached. We have an API for credit card processing, there is a doucment outlining what data needs to be pushed and what responces are expected from the API (this is done with XLM, and must be SSL secured). We need to have this API call integrated into the checkout process. In the zip file are two word docs, one is [login to view URL] and the other is the API manual.
