Build me a web site

Hi mate, I need a website builder, I need a dynamic site like www.sportsdirect.com the skeletal framework is ok if you can show me how to upload products subsequently, I can take it up from there. As I have a good knowledge of computer. I know the reference site in Question cost so much money and I am not asking for exactly same thing. A website that have a closer look alike is ok as I don’t have that huge fund for a Pro site like that. A budget of $150-$250 is ok as you only build the skeletal framework while you show me on how to upload product pictures and other navigation pages I can do all those ones by myself. Our business is growing and if you can give us something good you will definitely grow along with us. Thanks
