Just a caution about the fruit. The problem with fruit for guinea pigs is different than that for people. In people, we worry about cavities, obesity and diabetes. In pigs, while diabetes is a possible problem, the main concern is that too much sugar affects the balance of the food in the digestive tract. Guinea pigs are hind-gut fermenters, meaning that much of the work of digestion is done in the large intestine, rather than farther up the digestive tract in the mouth and stomach. If that balance gets out of whack, the pig can develop diarrhea or bloat, both serious problems for GPs.
So limit the fruit and sugary vegetables to just occasional tidbits, and instead feed leafy green vegetables, bell peppers and herbs. That sample menu link I gave you has some excellent information.
