Depends on the exact nature of the sports equipment and what kind of pictures he wants.
Action shots?
People modeling the equipment?
The equipment against a bare white background? (eBay-auction-style)
If equipment against a bare white background, there are quite a lot of instructions for DIY product photography studios out there. For smaller stuff, I've actually gotten good results from my old camera using a cardboard box lined with white card stock with a bunch of Sylvania CF bulbs from Sams' Club lighting the insides of the box. (white card stock = good WB reference.
You WILL need a WB reference when using the cheaper CFs, while most of them don't seem to have the classic greenish cast of fluorescents any more, they are color balanced to match tungsten and not daylight.)
