Do you have a window with privacy? I like natural light best, and a big window, with or without sheers is, in my opinion, the best light set up there is.
Take a look at B&H Photo and video, Adorama, Samy's online. Look for a two-light kit that comes with 2 stands, 2 adjustable lights and two umbrellas. There are small travel kits that will do the job.
You can probably get a light weight tripod for $50-ish dollars.
