Integrating Klarna (API) not moduel) + Joomfish in VMart

Hi there, I need an experienced developer who is able to integrate klarna (step by step guide here: [login to view URL]) manually (so not using their module - this is because it's not the latest virtuemart version and their module is not compatible with that) using their API. Also - I need Joomfish properly integrated with virtuemart, paying special attention to correctly displaying the product attributes in virtuemart. I will provide a back-up file of the site (SQL+files) so you can do the work locally or on a test server and I want the modified files only including a .txt file with your instructions on how to integrate the changes you made to the live site. Thanks!
