Don, if you and your guys decide at some point to make an affordable trip down here, here are my thoughts. Most stay and play resorts in TX can be very expensive, so here's a cheaper scenario.
First, I would probably stay at
Garden Valley near Tyler TX. Tyler is about 2 hours east of DFW, and an easy drive once you get out of the Metroplex. You can play golf there, and then make short road trips to 2 other courses,
Pine Dunes and
Twin Lakes. All 3 courses are outstanding, and are particularly fun in the spring when the azaleas and dogwoods are blooming. I will tell you that Pine Dunes is a big boy course, and be a tad tough if you guys play from the tips.
I certainly won't offer any swing suggestions, but it sure sounds like the driver's club face is wiping across the ball at contact and creating too much side spin.
If it was me, I would probably get some $2 driveway markers, and have a friend take some phone pics of both my ball position, and body alignment. Pics from the side and back can sure tell you a lot before you ever swing the club. If the camera allows it, I would also take those same shots with slo-mo video enabled on the phone. All this should at least let you know where you're at right now.
The only real issue that I have with lessons from a qualified PGA professional, is the transition time that it takes to get from one swing to another. My personal experience with high school golf teams is that one can get trapped between a "corrected" swing, and the old one, and one tends to revert to a swing that at least keeps the ball in play. Practicing with one swing, and playing with another sure makes the process difficult.
I think Lee Trevino said it best when he said "You can talk to a fade, but a hook won't listen". There's a lot of truth in that, and you're pretty close to that scenario, so any changes I might make would start out being very minor. In short, refine the swing you have before you rebuild it from the ground up.
Hope this helps, it's just my 2 cents.
