Custom template and setup of woocommerce with custom checkout

We currently use zen cart and want to migrate to woo commerce, We have specific requirements for the checkout, and are looking for a coder to handel the install, customization, and migration to our requirements The requirements for template (please message us if you need screenshots of the design) Checkout It will be a custom template We require a postcode lookup functionality to save users time [login to view URL] Main functionality from woo commerce template We need custom paypal payment module, Where by if paypal is selected, when confirm order is clicked. instead of being directed to paypal, they are routed through our sister site “siteb” and no order item information is sent, when the user has completed payment, they will be directed back to “site b” then redirected to this woo commerce store. This is due to our main site “site A” not being supported by paypal, so it is very important that they are unable to see that the order has originated from “site A” (ideally we would want to use paypal express module, if this is possible please specify this in your quote) We want facebook connect functionality so users can use facebook to login and save them time Plugins we will have installed, offline credit card, cart notices, woo sidebars, shipping details.
