Building a Ecommerce website

Hi i am looking to set up a small e commerce website. I want to set up a website where i can sell jewellery, linen and other household things online. I want a interactive website. It should have a shopping cart and also i should be anle to manage it easily. One thing i want is to set up google ad sense using which i google can advertise on this website. I also want it to be made in such a way that incase a person searches for a website like this on google or any other search engine this websites name should come up right at the top. Maybe not at the top but like the first page. It has to look very attractive and professional. The paying mechanism has to be set up as well. You can get back to me with any questions u have. Thank you
