Basic Website with ecommerce/CSKart Checkout/shopping kart

We are currently marketing an item that we require a website for. The domain name and hosting has already been registered: www.abcircle.com.au. This will be a very basic project, so will not require a lot of thought. In fact most of the information will be pulled from our eBay listing: [login to view URL];rd=1&item=330347020987 The website will require CSKart/ecommerce/shopping kart checkout, whereby the user enters in their zipcode and it will provide the shipping price - I am happy to enter in all the zipcodes myself to save time - The designer will only need to set it up. Checkout will need be linked to my Paypal account with other options provided. An eInvoice will be provided to the customer. This website will only run for 3 weeks or so before we cancel it, just to sell 1 highly marketable product. As a matter of URGENCY, this needs to be done within a relatively short timespan - next 3-4 days maximum, so if you do nopt have the time, please do not bid. I have a relatively small budget as well, $250- $550 max. Thank you
