Convert Virtuemart Site to Magento - add features

I am looking for someone to convert our current Virtuemart site to Magento. This would entail the following: - design Magento site to look more like our current site. It does not need to be exact, but similar. - import all current product info (names, descriptions, skus, prices, photos, etc) into new site - import current customers into new site Additionally, I need the following features added: - prices for wholesale customers. I can provide this as a spreadsheet or csv file. These need to be available only for customers registered a wholesale customers. - option to specify future date for shipping - option to select "account" for payment and not have to take a credit card on site. - option for some products to only be available for wholesale customers - ability to sync data (inventory, orders) with quickbooks pro I can provide a url to our current site if you'd like. Just request it and I will send a PM. Please specify how long this would take, show other sites you have done, and be clear on whether you can create all of these features.
