If I was going to do this I would do whole tenderloins and slice them. This was you can get a few done temps out of the entire loin. This works out great. I would also give the option of two different traditional sauces, bearnaise and bordelaise. Serve it will a nice side of infused flavored potatoes (not garlic) and some nice fresh grilled vegetables. It is very hard to price this out for such a small party. I would set in your minimum take for the day plus your food cost. There is not much prep involved with my menu.
