You don't need a high-end lighting setup to take well-lit photos. Use your tablet or smartphone to do some light painting for your shots.
Digital Photography School explains how to create the kind of shot above. It involves taking a few photos of your subject with the light in focused on different spots, then composing the final image in Photoshop and using layer masks to show the good light spots and hide the bad ones.
If you want to add some special effects or patterns, you can install some tablet-friendly softbox images on your tablet, but otherwise, all you need to get nice lighting effects is your mobile device.
