These run about ten dollars and you can use the clamp to attach it to a tripod or just about anything that you need to! Next you’ll need a good fill light, you’ll want to get a white chinese lantern.
Chinese lanterns are inexpensive and great at diffusing light. If you need something a little more powerful I recommend a work light.
Be careful with these because they get really hot. I’d also recommend bouncing them off a wall because pointing them directly at your subject may be a bit too harsh. FInally, if you are shooting outside you’ll want a reflector. For this you can simply use a white sheet of posterboard to reflect the sun back at your subject.
