Need to Migrate away from Ebay

I have a successful auto parts business on ebay, and I would like to create my own site so I can start migrating away from ebay and their fees. I ship worldwide, so ebay's entire listing interface is extremely necessary for me, which is why I don't know where to start for designing my own site. I need a site that can give accurate worldwide shippong estimates to buyers so that they can purchase items right away- I've learned that this is a big part of why I sell worldwide; people don't want to wait for me to receive an email order, especially if they don't speak English- they just want to pay and be done with it. Does anyone know what service I can use to design a site that incorporates these necessary ebay features?
