Shaun... bite the bullet and get your self a good compact camera!
I did once work for Panasonic and their cameras were really good, invest in a tripod and don't rely on artificial light too much... i find opening the curtains and letting as much light in the room is best...
Set your camera on a tripod and turn off the flash, try a slower shutter speed but make sure the camera is perfectly still !
Nothing worse than seeing other peoples work on your own website !
