Hey Linh,

I suggest you post in Internet Marketing forums like here and Warriorforum for people who have a list in this niche.

Otherwise, there is no other option other than to buy the lists.

Or you can also set up a squeeze page and rank it high on Google for your keyword. It will be the best way but the most time consuming too, taking upto 2-4 months to rank if the competition is high.
