I've used interquad for my training (MS Partner) and been happy with them, no idea if they have an office near you though. Depending on the length of course (days) you might get some discount, I organised courses for 4 of us here which came to about 30 days training, after a bit of haggling I managed to get the courses for 1/2 price due to the number of days we'd booked... might work for you also.
