DNA sequencers are not that expensive [1]. And I’m told the actual lab work is not that hard or dangerous (high school level?).

I fact, the database correlating millions of people’s DNA with their medical history and migration history is probably the hardest part.

But the potential market is there. I’d gladly play $1000 to have my sequence, even unanalyzed, with the knowledge no one else does.

1 cursory look at eBay. I don’t know if those sequencing machines are good for human DNA - I hate bio.
