I need to take quality of pictures of jewelry in consistent conditions for a business I am trying hard to set up (in the UK). Hence my budget is limited and I will have to do it myself, though I am inexperienced.

I have a digital camera (and photoshop which I intend to learn) but need a lighting set up that will be easy to set up and use, and not too big. Natural light can be great but far too unreliable and variable. Apart from getting myself a little tripod, I would be extremely grateful for advice on kit for lighting - what to get, how to use, and where from. I want to take pictures on a white background which I will use on a website and for marketing material. If you can help - in 'layman's terms'! - it would be really appreciated. Thanks!
