Create a standalone page with purchasable products ?

Hi, so this may be something im overseeing or if i need to manually add code perhaps, but what im looking for a special offer page to hand out to individuals wanting to promote my products.

it would be password protected but when they come to the page it will have the product on i want to have discounted down to a wholesale price for a one time purchase, so i dont want quantity available for selection. but when they click add to cart they will be cycled back to the main website.

For the most part i understand how to do everything but i was hoping for an ‘Add Product’ to the pages section, and didnt get lucky, that or im overlooking a simple addition to make it happen.

Any advice or best place to start to make this happen?
