Look at www.chilazexpress.com.
it's not exactly white goods, but it's still electronics shop.
The platform is flexible and customizable, so I can make it look as you want. Actually the sky is the limit. The budget will be between 300 and 500 EU, depend on the complicity of the project.
you may need to purchase some modules if you have specific requirements, and they cost between 10 and 50$ (average).
The timeline suggesttion :
day 1 : Shop installed;
day 1-3 : customization of the fuctionality, payment gateways, shipping methods and cost, category and products structure, login gateways;
day 3 - 7 : customization of the design and client side look;
The price DOES NOT contain the products entry, but if you can provide them in excel table/xml or API feed I can help you import them.
We usually work with 3 milestone payments :
1. in Advance 15%
2. After the functionality customization 60 %;
3. after the design finalization 25%
