Have you asked a brick-and-mortar eyeglass shop how much they’d do it for? Independently run places tend to be a lot more accommodating in my experience, and asking’s free.
Considering how much of a PITA cutting and drilling your own lenses sounds like it would be (not to mention the possibility of breaking them in the process and having to get new ones), it’s worth asking a couple of different shops first.
