I will echo the comments above, slightly
Pretend you go down the DM path...
You will pay for the DM course ($$$)
You will then need insurance (~$375-450/yr)
You will then spend your time diving in the shop recreational configuration and setting up OW students in rental gear and watching those students kneel... (lots and lots of your available diving time)
For that level of time and effort you could buy a set of doubles and take intro to tech (or GUE-F or cavern or something entry level-ish), and probably still have $$ left over.
