I believe this should be a simply project for someone familiar with Joomla & VirtueMart.
I have Joomla & VirtueMart installed on my test site. www.SpecialCouponOffers.com. I need to have USP & USPS live shipping configured (I have the accounts with USP & USPS already) as well as a Cybercash payment module configured and installed.
I'll be available all day and evening via email or IM today to get this done.
