I have a client who wants a family portrait of 22 people the day before Thanksgiving. Problem is, not everyone can arrive from traveling until 6pm, so it will be dark outside. I'm obviously going to try and arrange at least a few shots indoors, but the client wants at least one outdoors.

I know this will be tricky to get an impressive photo, but any advice on lighting? I don't think there will anything of particular interest on the house exterior or landscaping that I will want to expose into the picture. I'm only semi-pro (just charging small amounts to pay for my equipment and gain experience) and shoot a Canon XSi with an EF-S 17-55 f/2.8, an EF 50mm f/1.8 and have a Speedlite 580EX II. The best idea I've come up with now is to bring a couple halogen work lights and add fill with my speedlite.
