Seek is really the best place for what your are looking for.
Unfortunately like everything else, it's a numbers game and the more conversation you start, the better a chance you'll get..
Be careful, there's a lot of scammer and one word of advise I can give, do not part with money until the deeds is done. First time meet and drinks are fine but otherwise, I know of many that will try and hook up for a free dinner at a high class restaurant, only to fake sickness after - rinse and repeat.
Treat your initial few meets like a business transaction, and depending on rapport.. you can relax after you've built the trust
Not that say that you should be rude or disrespectful, but just think with your head rather than what's in your pants.
