Adding other products to bottom of product info page

I have a client that is using zencart ONLY for product ordering. The main site is separate, including all of the promotional and information text on products. Basically, he want to add a "Buy Now" link to his main site that goes to the specific product page and bypasses the other functionality of the cart.

Easy, right? But no....

He only sells 4 products, so he wants at the bottom of every product info page..."Also available from Acme Co" with a listing of his other 3 products. So really- every product page would be essentially the same, but the product clicked on would be the one shown at the top.

I was thinking that I could use Featured Products or Specials to do this- but it doesn't look like those show on the product info pages in the center column. Then I was thinking maybe using a cross sell mod- but those modify core files, so I want to make sure that is the best route before I go there.

Also, I need something in a tabular display, not columnar. Or something that can be readily hacked to be so.

I thought the All Products listing would be sufficient, but they want different pages with the selected item at the top. Here is what we have going:

Sorry if I am rambling...I am getting frustrated that I am having to dumb down and hack Zencart so much so that it will do exactly what they want. I don't think they realize how awesome it is as is...sigh...

Thank you in advance for any help.

Hi there - did you get this sorted? And if so, how?

If you are looking for something "special" then dont expect it is available right out of the box.
Also, who said that cross sell modifies core files?
