Hi Inkan,
It would be hard for anyone to give you a quote without understanding the details of what you are selling and exactly what you want your website to do for you (over and above selling products).
My basic e-commerce package is $1995, and this is for all standard features, and no additional customisations such as adding blogs, customer loyalty programs, email marketing set up which all add to a successful online business model.
I would recommend you talk to a web developer and outline all the details of what product you are selling AS WELL AS your ideas for marketing it online and offline, so that you get not just a website but one which is designed to work for you.
It is also important to listen to their expertise when it comes to what will work best. Too many times a client can be so prescriptive in what they want, that we end up creating a website exactly to their specifications, but one which does not work to fulfil its purpose. So use the expertise of your web developer.
regards
URsh
