The quality of your lighting is as critical as the quality of your camera. Natural is best, but light bulbs are easier to control and predict than the sun.
Again, take inventory of what you have. You surely have some form of artificial light.
If you live somewhere with predictably blue skies, work outside. Work next to a big window if you can but not if the sunlight is too direct.
You can take quality pictures in a cave without fancy artificial light. Desk lamps or work lights with clamps or flexible necks are very handy. You might have something in your garage, office or living room you can repurpose at no cost.
If you do need to buy some lights, get ones you can use for other stuff. Gooseneck floor lamps are great because you can move them around and aim them wherever. Lamps for use in a garage are durable, powerful and designed to mount in awkward spots like under the hood of a car. They're good too.

Then you need a big box. Cut the top and two sides off it and you're in business. Cover the inside with plain white paper to reflect light. No need to be fancy because only the poster board will be in the shot.
