UW camera purchase advice

Hi new here. Looking at setting up my first underwater camera system. I currently have a Sony A7RII already for travel and a GoPro Hero8. I am trying to keep my budget sub $2k as this is my first UW set up. I would like my camera to mainly do stills while the Gopro is mounted to record video simultaneously.

I was looking at getting the Seafrog version2 housing, a video light w auto off for strobe, and a strobe(needs to use sync cable). I've seen online the SeaLife 3000 light, Inon Z-330 strobe or Ikelite DS51 using sync cable. Housing $600, cable $100, video light $450, Inon $650 orDS51 $450, and then setting up the tray.

Alternatively, am I better off just getting something like the Sealife DC2000 w/ Pro3000 Set that includes camera, housing, strobe, and light?

Also, recommendations on the equipment to swap out that is still budget conscious?

Thank you

the usual question we ask here is diving experience, and how many dives or trips per year.     A housed camera is a massive undertaking, and not at all advised for those who still having to think about what they're doing to survive underwater.    For those, I'd say just take the Hero and remember not to crush the reef as you position for shots.

But even for an experienced diver, it's a big leap, and for the vacation diver, the first couple days get you back up to speed.  If you're doing 30 dives over a week, that's fine.  If you're just diving 2-3 days, use a simpler compact.  (sony RX, Canon G7x, Pansonic LX100 or similar 1", Olympus TG).

Housed SLRs and budgets of any reasonable size are also tough.   Housings can be 4k.   Dome ports can be 1-2k, and start at 500.   Used gear, and rentals are good bridge as you feel it out.   Your model being the II, you do have good shot and finding some stuff as people upgrade.

If you're fortunate enough to have easy access to a pool (esp your own), you can build a lot of currency with pool dives.   Easier to practice macro than WA, but for both can practice using the housing controls rather than the direct buttons.   You want to have finger memory so you can do changes while still focused on the target, or any other in water concerns.
