My stepdaughter went on 100 dates while in her teens (like, while aged 16-18), to get to know a variety of people (clean, usually double dates). She married ~#72 and they're doing very well, like, idyllic, after some years (she has blogs about raising their children). Anyway, while still a teen, she had an ebook published about why those 100 dates were a good idea, with 365 ideas for free or inexpensive dates:

~$3. For what it may be worth from a relative. (You have to install the publisher's free ebook app, to read it though.)

(edit: I found eHarmony's approach, though not really their IT department, to work really well for me.)
