Customize a Magento Go Template

Hi, I need to customize a Magento Go Shopping cart template. I have a full list of what the website needs to be able to do. The most important thing is that the shopping cart needs to be integrated with eBay. I will provide pictures to be used on the website. I need a very close communication with me regarding what it needs to be done. I will need also to be trained on how things work around the website, so I can work on it later on by myself. The timeframe for me is not a concern, the project can take longer time to be completed as long as it is done right and I like the look and feel. The final product should be looking something similar to [login to view URL] Please feel free to ask me questions, communication is very important.
