Add currency conversion to my Virtuemart 1.1 site.

Problem: I would like to add currency conversion to my Virtuemart 1.1 site. As background - I did a trial installation last year and could see enable this - but never got it working. I hired someone to do the upgrade to Virtuemart 1.1 for me - and have never been able to get the currency conversion working. Its as if it was never installed properly with this upgrade - or was some file or setting became corrupted. I expect that someone with some experience with Virtuemart currency conversion may be able to get this working for me. I am aware of further Virtuemart extensions that further work off the basic converter to give more options and functions. I would be open to suggestions re use and configuration of these as well to augment the site. I would like this developed and demonstrated on a pre-production site ([login to view URL]) , the changed/added files and settings advised so I can perform this on the live site and verify. Tasks: 1) Configure currency conversion to my Virtuemart 1.1 pre-production site http://upgrade.valleygreentea.com.au. Would pay say 80% of quote for this stage 2)Advise the solution (ie files changed) such that I can successfully apply the fix/themes/templates successfully to our production site (http://www.valleygreentea.com.au.) Would complete payment for this task. Further optional task 3) Advise any further extensions, augmentations ( happy to be quoted additional for this task) I will arrange temporary FTP access to this pre-production site for the developer
