Depending on the size of your male he could go quite a while without eating and sometimes changing things around such as bedding or enclosure size might be more than enough to get him back on food.
If your BP feeds F/T and you decide to feed live you might regret that as he may not switch back.
As for finding live feeders, you can find them at specialty pet stores, that sell reptiles and feeders, or you can check you local craigslist.
