If I were you I would take that time to train him myself, spend as much time with the pup in order to bond. Before 6 months, that's where primary socialisation takes place the most. I didn't have a trainer until my dog was 9-10 months, and it was only for consultation, never to learn basic obedience/tricks. I teach him all basic obedience, tricks and manners.
But if you still want to proceed. At 14 weeks, I will just expect him to learn a good sit, stay, leash walking, no pull, probably down. Just the basics.
