WHMCS payment gateway module - eWay transparent redirect

I require a payment module to be created for WHMCS. The default WHMCS eWay module using the eWay shared page, like paying by paypal for example where the user goes to paypal to pay. However we would like to have customers remain on our site for their payments using eWays transparent redirect. The bulk of the code and examples can be found at [login to view URL] It just needs piecing together to work in whmcs. Bidders must have good knowledge of whmcs, php, smarty php and ideally previous experience of creating a payment module for whmcs. This should take someone familiar with whmcs 1-2 hours to get the code together and another hour for tweaks at most.
