Hostbill integration with vcloud director

I'm looking to integrate Hostbill software with vCloud Director for automated billing and provisioning. I have some ideas about what features to include, but I would love ideas and input from an experienced professional - someone who can provide recommendations for creating a seamless integration while accomplishing my goal of automated billing and provisioning. Time is of the essence - I need this integration completed within a month. If you are experienced with both Hostbill and vCloud Director and can meet my timeline, please reach out so we can work together on this project.
