If you go to the pet trades, it says choose only lots with buyout. Click the box then apply.

Next to the search box there's a tiny button with a plus on it.

If you click it you get the advanced search options. Under intelligence type in the number you need and click search. Then you can order by cheapest buyout price by clicking on the little arrow next to "Buyout"
