I'm going there in a few weeks, so any info for a reliable female company would be much appreciated. 

Try with Florence from YFL.

Stephanie is one of the few established escorts In Nova Scotia. Reliable and gives good services.

Besides escort rankings, my usual go to website for checking Halifax escorts is Lyla. The Halifax escort community is really strong there.
