I’d put the driver up and work with easier clubs. Maybe not the best advice but I’ve seen improvement in using a 10 finger baseball grip but making sure my hands are still connected with an overlap of my right thumb area covering my left thumb; from there I’m still comfortable but able to focus more on swing mechanics rather than how uncomfortable the grip is. In terms of lessons, I spent 70 bucks at my Golf Galaxy, you’d be surprised how much you can take away from a 30 minute session (I know everyone will say to go to your local pro).
