I'm not sure where this exact desk comes from, but there are a variety of resources to find this sort of table. Here's a great list on Apartment Therapy: http://www.apartmenttherapy.com/sawhorse-tables-83858 Not sure if you can buy the legs separately as it sounds like you already have a slab. You could also try two nice wooden file cabinets as "legs" on either end of the slab. Good luck!

Thanks very much.

where can i buy this desk?
