uploading products to website

I am planning to launch a website and for that I need to upload products. No of prodcuts around 1000. Products will having many attributes,title,desc,images..etc.. if you are having experience in shopping cart i.e zencart/sunshop/interspire, then only bid for this project. You need to create category/sub category and upload [login to view URL] information will be in csv file but little messed up so cant load directly csv to website. Max budget - $100
