Oscommerce menu and cross sell

I need to have a cross-seel (x-sell) section placed in my product descriptions for my webstore. I have a functional website, but this feature is not implemented in the product side. However I have this feature in the checkout page. I would need the following to be done: •save cart feautre when a customer logs in, places items in cart, then logs out. After login again then items in cart are not there, I want the items placed in cart to be available/visible when customer returns. At the moment this is not implemented. •Cross-sell (x-sell) feature is not in the product page. I would like this feature in the product page •Top menu in the product page (see pic). This is not visible at the moment, I would like this to be shown/visible so customers can easily go into categories/subcategories I would like to pay $40.00 for this to be implemented and for the job to be done in 1 day. Timing is very important to meet this deadline. Bid on this only if you have EXPERIENCE with Oscommerce and can edit oscommerce template.
