Potty training help

I need some advice from someone who has been through this already. We just brought home our 10 week old beagle New Year's Day, and we are trying to potty train him. We try to use puppy pads inside when we are not home, and are trying to teach him to go outside when were home. (I know he cant hold it 8hrs while we are working that's why we want him to use puppy pads to) when he pees in the house we take him over to the puppy pad and he doesn't want to use it, and he won't pee for the next hour or so. And we take him outside every hour and the whole time he's outside he's scared to death and he won't use the potty. Any tricks? Or help? How long till he gets trained. We've had him 4 days with no successful potty attempts.
