design new website and upload products via date feed

if i was to give you my ebay affilate details to the winning bidder could someone design me a website and take a data feed from 1 ebay shop and upload to the website naturally my intentions are to promote this ebay sellers goods via my website and direct them back to the ebay shop, where hopefully they will buy the ebay goods and ebay will pay me commision. is this something any body can do from start to finish. also how long would this take and how much will it cost look forward to many responces regards andrew marr
