I am more than happy to chat about the limited dive knowledge I have. It is a hobby that I only recently picked up in the last few year and I still and gaining lots of knowledge. I am lucky in that I have gotten to do most of my dives with very experienced divers.
You don’t have to break the bank on a camera. eBay has lots of Canon Powershot cameras that have decent but inexpensive housings like this

I actually bought the Canon Powershot G9 which is a step down from the G12 for around $240 USD. The only drawback of the Canon cameras with the “factory” housings is that you may not have every camera setting function with the housing. If you bought an Ikelite house which would cost 3x the camera price you would get full functionality. They are just some manual camera settings that I just commit to before I get in the water. I am still learning the settings on my camera so I may be able to set it up differently.
Sounds like your recreation property will be a great opportunity for diving. My family has a house in Tahsis and that is why I mainly got into diving. It gave me something to do there in the fishing off season and is a unreal spot to dive.
I wonder if there is enough diving interest to have a sub forum about diving.
