Hi Gil
The easiest solution is to use K Type thermocouples with the ThermaQ Blue. You can
see details here.
The ThermaQ Blue cal be purchased
on the Thermoworks website here. They ship internationally.
As far as the thermocouple probes themselves, you can buy them from Thermoworks, or anywhere online. Just make sure they are K Type probes with the yellow "quick connector" on the end. I, myself, prefer shielded (ungrounded) probes, because their temperature reporting is smoother (albeit a little slower). Just make sure they are sized appropriately for your roasting chamber. Thermocouples CAN be bent for fitting, AS LONG as you do it on a radius (no sharp bends - only curves), and you don't bend within an inch or so from the tip where the actual junction is located.
Amazon is a good place to look for probes.
