This is terrible for many reasons, one of which is that no one will actually meet anyone else in real life and no one wants to talk to a dating bot. Once that's exposed you'd lose all credibility.

For heterosexual relationships: you need real single women. If you have that, the men will show up and they'll be easy to attract. You might consider locating single women in several age groups (not sure how to do this, perhaps marketing) and asking them to join, you could potentially pay them for signing up and creating a profile. I'm not sure what that amount is but it's probably not that expensive.
