Newbury Electronics "PCB Train" could probably put them on for you.  Might not be too expensive for a small prototype batch?

I wouldn't fancy my chances soldering something like that manually myself. I've done various QFNs without the thermal pads, but in your application getting a good low thermal resistance is important to get rid of heat to the PCB via the thermal pads. And those areas of copper for sinking the heat will make it harder to solder manually! I'd say pre-heating the PCB with a hot plate would be essential. Just my thoughts.
