Help installing joomla virtuemart theme

I have joomla 1.5.22 installed and have bought the Yagendoo Vamazing theme. I thought they would provide good installation instruction with samples but they didn't and worse still, will not give any support. I have tried to install it, but as a newby to Joomla, do not know joomla, virtueMart or themes well. This is what I have so far. [login to view URL] I have a link to the theme but that is all.. I would like to have the Yagendoo installation done to my joomla so that it looks like what they have on their demo. That is why I bought it and want it to look like. [login to view URL] I need someone to install it just like the demo using some products and images so I can see what it looks like in Admin to get to understand it. Set up maybe 4 categories with 3 products in each would give me an idea how it works. If you have better installation instructions I wpould like these as well for the future.
